Check Digit Verification of cas no

The CAS Registry Mumber 1187020-64-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,7,0,2 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1187020-64:
(9*1)+(8*1)+(7*8)+(6*7)+(5*0)+(4*2)+(3*0)+(2*6)+(1*4)=139
139 % 10 = 9
So 1187020-64-9 is a valid CAS Registry Number.

Bazargan, Leila,Shafiee, Abbas,Amini, Mohsen,Dezfouli, Ebrahim Bakhshi,Azizi, Ebrahim,Ghaffari, Seyed Mahmood

experimental part, p. 602 - 609 (2009/10/02)

A series of 4-[2-methyl (or aryl) thiazole-4-yl]-2,6-dimethyl-3,5-diacetyl (or dibenzoyl) 1,4-dihydropyridines were synthesized using a modified Hantzsch reaction involving the condensation of the corresponding aldehyde with acetyl acetone or benzoyl acetone. The preparation of the corresponding aldehydes (2-methylthiazole-4-carboxaldehyde and some 2-arylthiazole-4-carboxaldehydes) was achieved by a simplified protocol of the published synthesis.
