127232-99-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127232-99-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,2,3 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 127232-99:
(8*1)+(7*2)+(6*7)+(5*2)+(4*3)+(3*2)+(2*9)+(1*9)=119
119 % 10 = 9
So 127232-99-9 is a valid CAS Registry Number.

The β-Effect: Changing the Ligands on Silicon
Brook, Michael A.,Neuy, Axel
, p. 3609 - 3616 (2007/10/02)
The ability of a silyl group to stabilize a carbocation β to silicon, the β-effect, is directly related to the electron-withdrawing ability of the groups on silicon.This was shown by using the degree of syn addition of bromine to (E)-β-silylstyrenes as a
