Check Digit Verification of cas no

The CAS Registry Mumber 1333237-90-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,3,2,3 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1333237-90:
(9*1)+(8*3)+(7*3)+(6*3)+(5*2)+(4*3)+(3*7)+(2*9)+(1*0)=133
133 % 10 = 3
So 1333237-90-3 is a valid CAS Registry Number.

Synthesis of some new triazole incorporated imidazo [2,1-b]-1,3,4- thiadiazoles

Wang, Yan-Fei,Shen, Guo-Liang,Li, Rong-Shan,Dong, Heng-Shan

, p. 403 - 404 (2013/09/24)

A series of 6-[5-methyl-1 -(p-tolyl)-lH-1,2,3-triazol-4-yl]-2-substituted imidazo [2,1-b]-1,3,4-thiadiazoles 7 were synthesized by the reaction of 2-amino-5-substituted-1,3,4-thiadiazoles 6 with 2-bromo-1-[5-methyl-1-(p-tolyl)- 1H-1,2,3-triazol-4-yl] ethanone 4. Their structures were confirmed by 1H NMR, MS and IR spectra.
