1137172-09-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1137172-09-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,7,1,7 and 2 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1137172-09:
(9*1)+(8*1)+(7*3)+(6*7)+(5*1)+(4*7)+(3*2)+(2*0)+(1*9)=128
128 % 10 = 8
So 1137172-09-8 is a valid CAS Registry Number.

Bratulescu, George
experimental part, p. 350 - 352 (2012/08/07)
Imidazo[2,1-b]thiazole derivatives were obtained from 2-aminothiazoles or 2-amino-2-thiazolines and 4-chloromethyl-co-bromoacetophenone in three steps. The product syntheses take place in convenient conditions with yields between 50 and 70 %.
