The CAS number called for on a Material Safety Data Sheet is the Chemical Abstracts Service registry number of the material. The Chemical Abstracts Service issues a unique number to each chemical that is mentioned in a scientific article abstracted by the Chemical Abstracts Service, and also to some complex mixtures. The number has no intrinsic meaning; it merely points to a specific chemical. It's value is that it is an unambiguous reference to a chemical, whereas there are frequently more than a few ways of naming each chemical using words and structural descriptions.
