CAS
The CAS number or CAS registry number for a chemical compound, polymer, biological sequence, and alloy is a number with a unique record in the database of the Chemical Abstracts Service, a division of the Chemical American Society .
The Chemical Abstracts Service assigns these numbers to each chemical that is described in the literature. Furthermore, CAS maintains and markets a database of these substances: the CAS Registry (according to Wikipedia. Accessed on 06/05/2023).
