Check Digit Verification of cas no
The CAS Registry Mumber 618398-67-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,8,3,9 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 618398-67:
(8*6)+(7*1)+(6*8)+(5*3)+(4*9)+(3*8)+(2*6)+(1*7)=197
197 % 10 = 7
So 618398-67-7 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
