Check Digit Verification of cas no
The CAS Registry Mumber 91590-52-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,5,9 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 91590-52:
(7*9)+(6*1)+(5*5)+(4*9)+(3*0)+(2*5)+(1*2)=142
142 % 10 = 2
So 91590-52-2 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
