74195-31-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74195-31-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,9 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74195-31:
(7*7)+(6*4)+(5*1)+(4*9)+(3*5)+(2*3)+(1*1)=136
136 % 10 = 6
So 74195-31-6 is a valid CAS Registry Number.

Extrusion of Sulfur from pyrimidinones
Roth, Barbara,Laube, Renee,Tidwell, Mary Y.,Rauckman, Barbara S.
, p. 3651 - 3657 (1980)
Thermally mediated sulfur extrusion from 4-(phenacylthio)-2(1H)-pyrimidinones occurs rapidly in solution at 125 deg C to yield 4(3H)-(benzoylmethenyl)-2(1H)-pyrimidinones. 4-(Acetonylthio)-2(1H)-pyrimidinone, however, rearranges via an episulfide intermed
