374784-55-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 374784-55-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,4,7,8 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 374784-55:
(8*3)+(7*7)+(6*4)+(5*7)+(4*8)+(3*4)+(2*5)+(1*5)=191
191 % 10 = 1
So 374784-55-1 is a valid CAS Registry Number.

Synthesis of 2-pyridones as tissue factor VIIa inhibitors
Parlow, John J.,South, Michael S.
, p. 7695 - 7701 (2007/10/03)
2-Pyridones were prepared from 2,6-dibromopyridine via a multi-step synthesis. A variety of chemical transformations, including regioselective nucleophilic addition and selective nitrogen alkylation, afforded the penultimate intermediate 9. A combination
