Check Digit Verification of cas no
The CAS Registry Mumber 80532-67-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,5,3 and 2 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 80532-67:
(7*8)+(6*0)+(5*5)+(4*3)+(3*2)+(2*6)+(1*7)=118

Benincasa, Marta,Forti, Luca,Ghelfi, Franco,Libertini, Emanuela,Pagnoni, Ugo M.
, p. 4113 - 4122 (1996)
Methyl 2,2-dihalocarboxylates add easily to carbonyl compounds in fair to good yields through the intermediate formation of 2-haloester enolates; the reaction is promoted by zinc, following a "Barbier" type procedure.
