Chemical Abstracts Service (CAS) is an organization that provides information about chemical substances. CAS maintains a registry of chemical substances, called the CAS Registry, which contains over 153 million unique chemical substances. Each substance in the CAS Registry is assigned a unique identifier, called a CAS Registry Number (CAS RN). CAS RNs are used to identify chemical substances in scientific literature, patents, and other documents. CAS also provides a variety of other services, including chemical structure searching, property prediction, and regulatory compliance support.
The A-Z Guide to Chemical and Biological Entities: A Fun and Informative Journey
Greetings, curious minds! Welcome to our quest to unravel the enigmatic world of chemical and biological entities. Today, we’ll venture into the heart of the topic, starting with core entities that are absolutely essential to understanding this fascinating field.
CAS Registry Number (CAS RN): Your Chemical Fingerprint
Picture this: every chemical substance under the sun has its own unique fingerprint, known as a CAS Registry Number (CAS RN). It’s like a super-secret code that identifies the chemical with pinpoint accuracy. No two substances share the same CAS RN, making it the ultimate ID card in the chemistry world.
Chemical Abstracts Service (CAS): The Gatekeeper of Chemical Knowledge
Think of the Chemical Abstracts Service (CAS) as the Google of chemistry. This organization gives us access to a treasure trove of chemical information, including those precious CAS RNs. They’re like the gatekeepers of chemistry, ensuring we can find whatever chemical data we need.
Related Entities in Chemical and Biological Information
In our exploration of chemical and biological information, let’s delve into some related entities that play crucial roles in organizing and disseminating this valuable knowledge. These entities may not be as indispensable as our core entities (CAS Registry Number and Chemical Abstracts Service), but they provide valuable support and complementary information.
-
Chemical Abstracts (CA)
The Chemical Abstracts database is a colossal resource that has been accumulating chemical information for over a century. It’s like a Wikipedia for chemistry, containing millions of abstracts and references on all aspects of the field. CA is a treasure trove for researchers and anyone seeking comprehensive chemical knowledge.
-
Registry of Toxic Effects of Chemical Substances (RTECS)
This database is your go-to source for information on the potential hazards of chemicals. It provides toxicity data on thousands of substances, helping us understand their risks and take appropriate safety measures. Think of RTECS as the watchdog protecting us from the dark side of chemicals.
-
European Chemicals Agency (ECHA)
The ECHA is the European Union’s watchdog for chemicals. It ensures that substances meet safety standards and provides access to information on their properties, uses, and risks. In essence, ECHA is the guardian of chemical safety in Europe, safeguarding both humans and the environment.
-
National Library of Medicine (NLM)
If you’re looking for information on biomedical and chemical literature, the NLM has got you covered. They maintain vast databases, including PubMed, which is an invaluable resource for medical research. Think of the NLM as the librarian of the medical and chemical world.
-
National Centre for Biotechnology Information (NCBI)
NCBI is all about the genetic code. They’ve got the largest collection of genetic sequencing data, including the Human Genome Project. NCBI is the master of genetic information, helping us unravel the mysteries of life.
-
PubChem
PubChem is like the Swiss Army knife of chemical databases. It houses a massive collection of chemical structures, along with information on their properties, biological activities, and toxicology. It’s a one-stop shop for anyone interested in the molecular world.
Well there you have it. I hope this cleared up any questions you had about CAS ID. If you’re still curious, feel free to drop by again later for more interesting and informative articles. Until then, keep exploring and learning!
