Check Digit Verification of cas no

The CAS Registry Mumber 401649-83-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,1,6,4 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 401649-83:
(8*4)+(7*0)+(6*1)+(5*6)+(4*4)+(3*9)+(2*8)+(1*3)=130
130 % 10 = 0
So 401649-83-0 is a valid CAS Registry Number.

Synthesis and transformations of 3-acetylpyridine-2(1H)-thiones

Zav'Yalova,Zubarev,Litvinov

experimental part, p. 1534 - 1538 (2009/10/01)

Reactions of substituted 3-cyanopyridine-2(1H)-thiones with methyllithium gave 3-acetylpyridine-2(1H)-thiones. The best results were achieved by adding a solid-state thione to a solution of methyllithium in ether (thione: MeLi = 1: 3). The compounds obtained and their 3-pentanoyl analogs were used to synthesize a number of fused heterocyclic systems.
