18748-61-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18748-61-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,7,4 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 18748-61:
(7*1)+(6*8)+(5*7)+(4*4)+(3*8)+(2*6)+(1*1)=143
143 % 10 = 3
So 18748-61-3 is a valid CAS Registry Number.

Reactions of α-epoxysilanes with organocopper reagents. A stereoselective route to alkenes
Chauret, Denise C.,Chong, J. Michael
, p. 3695 - 3698 (1993)
Reactions of α-epoxysilanes with cuprate reagents can be controlled to give β-silyl alcohols as major products. An oxidation, Grignard addition, and elimination sequence then provides alkenes with up to 98% de.
