Calculate Digit Verification of CAS Registry Number 129178-79:
(8*1)+(7*2)+(6*9)+(5*1)+(4*7)+(3*8)+(2*7)+(1*9)=156
156 % 10 = 6
So 129178-79-6 is a valid CAS Registry Number.

REGIO- AND STEREOSELECTIVE SYNTHESIS OF ALLYLTRIMETHYLSILANES VIA KRIEF-REICH ELIMINATION IN β-SELENO-γ-SILYL ALCOHOLS

Sarkar, Tarun K.,Ghosh, Sunil K.,Satapathi, Tushar K.

, p. 1885 - 1898 (2007/10/02)

The synthesis of (E)-allyltrimethylsilanes by regio- and stereocontrolled pathways is described based on the preference for Krief-Reich elimination over silicon-controlled rearrangement in β-seleno-γ-silyl alcohols, readily available from α-selenoaldehydes, 10 - 12.Usefulness of this protocol for the introduction of the allylsilane function α to the carbonyl group in cycloalkanones as well as for the preparation of unsymmetrically substituted allylsilanes is also reported.
