221052-16-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 221052-16-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,0,5 and 2 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 221052-16:
(8*2)+(7*2)+(6*1)+(5*0)+(4*5)+(3*2)+(2*1)+(1*6)=70
70 % 10 = 0
So 221052-16-0 is a valid CAS Registry Number.

Synthesis of 3-Cyano-6-methyl-4-(5-methyl-2-furyl)pyridine-2(1H)-thione by Michael Reaction
Dyachenko,Litvinov
, p. 696 - 698 (2007/10/03)
5-Methylfurfurylideneacetone reacted with cyanothioacetamide to give 3-cyano-6-methyl-4-(5-methyl-2-furyl)pyridine-2(1H)-thione which was used to prepare substituted 2-alkylthiopyridines and thieno[2,3-b]pyridines.
