874117-22-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 874117-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,4,1,1 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 874117-22:
(8*8)+(7*7)+(6*4)+(5*1)+(4*1)+(3*7)+(2*2)+(1*2)=173
173 % 10 = 3
So 874117-22-3 is a valid CAS Registry Number.

A novel one-pot approach to the imidazo[1,5-a]pyrazine system has been elaborated based on the cyclization of 3-[(2-amino-1,2-dicyanoethen-1-yl)amino]-2-(benzoylamino)propenoates with orthoesters.
