Check Digit Verification of cas no

The CAS Registry Mumber 1189178-91-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,1,7 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1189178-91:
(9*1)+(8*1)+(7*8)+(6*9)+(5*1)+(4*7)+(3*8)+(2*9)+(1*1)=203
203 % 10 = 3
So 1189178-91-3 is a valid CAS Registry Number.

One-pot synthesis of 2-substituted imidazo[2,1-b][1,3]benzothiazoles via coupling-cyclization under Pd-Cu catalysis in Water

Bakherad, Mohammad,Keivanloo, Ali,Hashemi, Mahdieh

experimental part, p. 165 - 170 (2010/04/23)

The reaction of 2-imino-3-(2-propynyl)-1,3-benzothiazole with various aryl iodides, catalyzed by Pd-Cu, in the presence of sodium lauryl sulfate as the surfactant and potassium carbonate as the base, in water, leads to the formation of 2-substituted imida
