74180-94-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74180-94-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,8 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 74180-94:
(7*7)+(6*4)+(5*1)+(4*8)+(3*0)+(2*9)+(1*4)=132
132 % 10 = 2
So 74180-94-2 is a valid CAS Registry Number.

Carbophilic reactions of an arylthio-substituted sulfine with α-oxo-carbanions
Leij, M. van der,Zwanenburg, B.
, p. 49 - 52 (2007/10/02)
The reaction of p-tolyl(phenylthio)sulfine 1 with α-oxo-carbanions is described.With 2-lithiocyclohexanone, sulfine 1 furnishes alkene disulfide 2.Similarly, the carbanion of 3,4-dihydro-1-naphthalenone (α-tetralone) gives dis
