224789-26-8 Molecular Info »Chemical products are described in many different ways including chemical structures, generic, molecular formulas, systematic, common, and trade names. The CAS (Chemical Abstracts Service) Registry Number (Cas No or Cas Number) is a unique identifier which is a unique and unambiguous identifier for a specific substance that allows clear communication and, with the help of CAS scientists, links together all available data and research about that substance. Governmental agencies rely on CAS Registry Numbers for substance identification in regulatory applications because they are unique, easy validated, and internationally recognized.You can search the Chemical compounds's molecular information with the Cas Registry Number.You can also Search Cas Number with Chemical Name or formulas.The most complete and comprehensive Cas number lookup on Molecularinfo.com.
