123044-04-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123044-04-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,0,4 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 123044-04:
(8*1)+(7*2)+(6*3)+(5*0)+(4*4)+(3*4)+(2*0)+(1*4)=72
72 % 10 = 2
So 123044-04-2 is a valid CAS Registry Number.

Synthesis of some bicyclic thiazolopyrimidine derivatives
Mobinikhaledi,Forughifar,Goodarzi
, p. 2539 - 2543 (2003)
Thiazolopyrimidine compounds 3(a-d) were synthesized by a simple one-pot condensation reaction of starting pyrimidine derivative 1 and 1,2-dibromoethane 2 in dimethylformamide. In a similar way thiazolopyrimidine compounds 5(d-e) were synthesized by react
