139952-77-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139952-77-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,5 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 139952-77:
(8*1)+(7*3)+(6*9)+(5*9)+(4*5)+(3*2)+(2*7)+(1*7)=175
175 % 10 = 5
So 139952-77-5 is a valid CAS Registry Number.

A new silicon-mediated elimination-rearrangement
Menichetti, Stefano,Stirling, Charles J. M.
, p. 1511 - 1515 (2007/10/03)
Treatment of trimethylsilylethanes bearing α-phenyl groups and β-phenylthio, phenylsulfonyl or cyano groups with LDA causes elimination-rearrangement mediated by the β-carbanionic species. Mechanistic conclusions are based on isotopic labelling experiment
