Check Digit Verification of cas no
The CAS Registry Mumber 354550-07-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,4,5,5 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 354550-07:
(8*3)+(7*5)+(6*4)+(5*5)+(4*5)+(3*0)+(2*0)+(1*7)=135
135 % 10 = 5
So 354550-07-5 is a valid CAS Registry Number.

Synthesis and reactions of polynuclear heterocycles: Azolothienopyrimidines and thienothiazolopyrimidines
El-Gazzar,Hussein,Aly
, p. 2771 - 2784 (2006)
We prepared a thieno[2,3-d]pyrimidine compound fused with a thiazolo ring to produce biologicaly active compounds. In a one-step reaction, 2-arylmethylene derivative (3) was prepared via the reaction of a ternary mixture of 2-thioxo-1,2,3,4-tetrahydrocycl
