Check Digit Verification of cas no
The CAS Registry Mumber 149379-73-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,3,7 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 149379-73:
(8*1)+(7*4)+(6*9)+(5*3)+(4*7)+(3*9)+(2*7)+(1*3)=177
177 % 10 = 7
So 149379-73-7 is a valid CAS Registry Number.

A Simple Synthesis of 2-Methoxypyridine-3-carbonitriles
Victory, Pedro,Borrell, Jose I.,Vidal-Ferran, Anton
, p. 769 - 776 (2007/10/02)
The condensation of propanedinitrile with several enals or enones in a methanol-sodium methoxide system provides a one-step route to 2-methoxypyridine-3-carbonitriles.Together with these compounds substituted 2-aminobenzene-1,3-dicarbonitriles, were obtained as by-products.
