128693-16-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128693-16-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,6,9 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 128693-16:
(8*1)+(7*2)+(6*8)+(5*6)+(4*9)+(3*3)+(2*1)+(1*6)=153
153 % 10 = 3
So 128693-16-3 is a valid CAS Registry Number.

Regiospecific Synthesis of 1-Silyl Substituted 1,4-Dienes
Schaumann, Ernst,Kirschning, Andreas
, p. 419 - 421 (2007/10/02)
The reaction of epoxysilanes with lithiated allylsilanes gives predominantly α-silyl-substituted alcohols (3) which are convenient precursors for the preparation of 1-silyl-substituted 1,4-dienes.
