Check Digit Verification of cas no
The CAS Registry Mumber 108472-67-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,4,7 and 2 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 108472-67:
(8*1)+(7*0)+(6*8)+(5*4)+(4*7)+(3*2)+(2*6)+(1*7)=129
129 % 10 = 9
So 108472-67-9 is a valid CAS Registry Number.

Synthesis and Properties of Quaternary Ammonium Salts of Substituted α-Phenylcinnamonitriles
Stewart, James T.,Kim, Myungsoo
, p. 387 - 389 (1987)
Quaternary ammonium salts of substituted α-phenylcinnamonitriles were synthesized via base-catalyzed condensations of substituted phenylacetonitriles and aldehydes, followed by alkylation of the amino moieties with dimethyl sulfate or methyl trifluorometh
