Check Digit Verification of cas no
The CAS Registry Mumber 109202-21-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,2,0 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 109202-21:
(8*1)+(7*0)+(6*9)+(5*2)+(4*0)+(3*2)+(2*2)+(1*1)=83
83 % 10 = 3
So 109202-21-3 is a valid CAS Registry Number.

Nouvelle methode de synthese de thiazolopyridines
Couture, Axel,Grandclaudon, Pierre,Huguerre, Eric
, p. 1765 - 1770 (2007/10/02)
It has been established that the direct condensation between aromatic and aliphatic thioesters and the variously generated anion of aminochloropyridines represents the best method for the synthesis of thiazolopyridines.The transient thioamides, sometimes isolated, can be easily converted chemically or photochemically into the desired fused heterocycles.
