FAIRsharing record for: Chemical Abstracts Service Registry

This FAIRsharing record describes: The CAS (Chemical Abstracts Service) Registry is the CAS substance collection, and is a division of the American Chemical Society and contains databases of chemical information. CAS Registry Numbers (often referred to as CAS RNs or CAS Numbers) are universally used to provide a unique, unmistakable identifier for chemical substances. A CAS Registry Number itself has no inherent chemical significance but provides an unambiguous way to identify a chemical substance or molecular structure when there are many possible systematic, generic, proprietary or trivial names.
