CAS Registry Numbers have no chemical significance in themselves and are assigned in sequential order as new substances are entered into the CAS Chemical Registry System. Each CAS Registry Number designates only one chemical substance in terms of atoms, valence bonds, and stereochemistry, insofar as that substance has been elucidated and defined. An asterisk after the CAS Registry Number indicates that it is not currently used in CAS abstract or index publications. 6, record 1, English, - CAS%20registry%20number

Les numéros de registre CAS n'ont aucune signification chimique en soi et sont attribués au fur et à mesure de l'introduction de nouvelles substances dans le système informatisé du CAS. Chaque numéro de registre CAS ne désigne qu'une seule substance chimique en termes du nombre d'atomes, des liaisons de valence et de la stéréochimie, dans la mesure où cette substance a été élucidée et définie. La présence d'un astérisque après le numéro de registre CAS indique qu'il n'est pas utilisé couramment dans les deux index et les résumés du CAS. 4, record 1, French, - num%C3%A9ro%20de%20registre%20CAS
