Why CAS Numbers Matter

Wiki Article

One of the most widely recognized identifiers in chemistry is the Chemical Abstracts Service (CAS) Registry Number. Each CAS number corresponds to a specific chemical substance, providing a consistent reference regardless of naming conventions or language.

Researchers use CAS numbers to:

• Locate scientific publications
• Search laboratory databases
• Identify safety documentation
• Order reference materials
• Compare analytical data

Because many compounds have multiple common names or synonyms, CAS numbers help ensure that scientists are referring to the same substance.
