74203-17-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74203-17-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,0 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74203-17:
(7*7)+(6*4)+(5*2)+(4*0)+(3*3)+(2*1)+(1*7)=101
101 % 10 = 1
So 74203-17-1 is a valid CAS Registry Number.

Extrusion of Sulfur from pyrimidinones
Roth, Barbara,Laube, Renee,Tidwell, Mary Y.,Rauckman, Barbara S.
, p. 3651 - 3657 (2007/10/02)
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
