Check Digit Verification of cas no

The CAS Registry Mumber 1131544-06-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,1,5,4 and 4 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1131544-06:
(9*1)+(8*1)+(7*3)+(6*1)+(5*5)+(4*4)+(3*4)+(2*0)+(1*6)=103
103 % 10 = 3
So 1131544-06-3 is a valid CAS Registry Number.

Synthesis and structure of some thienopyrimidine derivatives

Hamed, Atef A.,Zeid, Ibrahim F.,El-Ganzory, Hussein H.,Abdel Aal, Mohamed T.

, p. 809 - 820 (2008)

A series of substituted thieno[2,3-d]pyrimidines was synthesized starting from ethyl-2-amino-4-isopropylthiophene-3-carboxlate. Reaction of 2-hydrazino-5-isopropyl-thieno[2,3-d]pyrimidin-4(3H)-one and its 3-methyl analogue with different reagents afforded thieno[2,3-d]triazolo[4,3-a] pyrimidines and thieno[3,2-e]triazolo[4,3-a]pyrimidines, beside open chain derivatives.
