Check Digit Verification of cas no

The CAS Registry Mumber 1104641-83-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,0,4,6,4 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1104641-83:
(9*1)+(8*1)+(7*0)+(6*4)+(5*6)+(4*4)+(3*1)+(2*8)+(1*3)=109
109 % 10 = 9
So 1104641-83-9 is a valid CAS Registry Number.

Spectroscopic study of the keto-enol equilibrium of N- aryldiacetylthioacetamides and their reactivity

Zaleska,Burgiel,Serda

experimental part, p. 349 - 355 (2009/04/03)

An NMR study of the equilibrium between keto-enol tautomeric forms of N-aryl-diacetylthioacetamides enables us to estimate their population ratio in solvents of increasing polarity. An X-ray analysis confirmed the structure of the thermodynamically most s
