CAS Number Application


Background of the CAS Number

CAS Number Application

Chemical compounds are identified in many different ways, such as chemical structures, systematic names, and common names. This ambiguity in the identification of chemical substances causes delays and even safety problems in the identification of chemical substances. As a unique and unambiguous identifier for specific substances (such as compounds, polymer materials, and alloys), CAS numbers help researchers, producers, traders, and users of chemical substances communicate clearly.

CAS numbers of chemical substances are always used in practical business activities, such as customs chemical filing, chemical trade, and chemical registration (e.g., EU REACH registration, Chinese new chemical registration, U.S. TSCA filing). CAS numbers for most common substances are available in publicly available databases, but for patented or newly generated substances, CAS numbers can only be obtained by application to the CAS (Chemical Abstract Service).
