Despite their utility, CAS Numbers have some limitations:
Not Descriptive: CAS Numbers do not convey any chemical information about the substance, such as its structure or properties. Not Comprehensive: Some substances, particularly mixtures and formulations, may not have a specific CAS Number. Proprietary Compounds: Certain proprietary or confidential compounds may not have publicly available CAS Numbers.
These limitations necessitate the use of additional resources for a comprehensive understanding of the substance.
