Check Digit Verification of cas no
The CAS Registry Mumber 89991-60-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,9 and 1 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 89991-60:
(7*8)+(6*9)+(5*9)+(4*9)+(3*1)+(2*6)+(1*0)=206
206 % 10 = 6
So 89991-60-6 is a valid CAS Registry Number.

-
, (2008/06/13)
A phenylethyl substituted dimer of ethylene and maleic anhydride, names 7-phenyloctane-(1,2),(5,6)-dianhydride, is chemically synthesized by (a) alkylating alkyl 2,4-dihalobutyrate with alkyl 2-cyano-3-phenylbutyrate, (b) alkylating the resulting
