Check Digit Verification of cas no

The CAS Registry Mumber 18187-22-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,1,8 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 18187-22:
(7*1)+(6*8)+(5*1)+(4*8)+(3*7)+(2*2)+(1*2)=119
119 % 10 = 9
So 18187-22-9 is a valid CAS Registry Number.

Effect of substituents on the silicon atom on etherification of organochlorosilanes with ethanol

Chernyshev,Belyakova,Komarov,Bykovchenko

, p. 1038 - 1040 (2007/10/03)

The kinetics of etherification of organochlorosilanes with various substituents on the silicon atom with ethanol were studied. The etherification rate is mostly controlled by the inductive constants of the substituents and increases as the electron-acceptor power of the substituents increases. The ρ* value in the Taft equation for etherification of organochlorosilanes with ethanol was determined.
