Check Digit Verification of cas no
The CAS Registry Mumber 105774-90-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,7,7 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 105774-90:
(8*1)+(7*0)+(6*5)+(5*7)+(4*7)+(3*4)+(2*9)+(1*0)=131
131 % 10 = 1
So 105774-90-1 is a valid CAS Registry Number.

CYANOTHIOACETAMIDE IN HETEROCYCLIC SYNTHESIS. A NOVEL SYNTHESIS OF 2-PYRIDOTHIONE DERIVATIVES
Fahmy, S. M.,Mohareb, R. M.
, p. 687 - 690 (2007/10/02)
Cyanothioacetamide (1) shows intermolecular cyclocondensation via refluxing in ethanolic sodium ethoxide solution to give a pyridothione derivate 5.Establishment of its structure as well as some of its chemical behaviour is discussed briefly.
