18602-90-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18602-90-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,6,0 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 18602-90:
(7*1)+(6*8)+(5*6)+(4*0)+(3*2)+(2*9)+(1*0)=109
109 % 10 = 9
So 18602-90-9 is a valid CAS Registry Number.

A new selective approach to unsymmetrical siloxanes and germasiloxanes via O-metalation of silanols with 2-methylallylsilanes and 2-methylallylgermanes
Hreczycho, Grzegorz,Pawluc, Piotr,Marciniec, Bogdan
experimental part, p. 2743 - 2746 (2012/01/11)
A scandium(iii) trifluoromethanesulfonate-catalyzed O-metalation of silanols with 2-methylallylsilanes and 2-methylallylgermanes leading to siloxane or germasiloxane bond formation under mild conditions with evolution of isobutylene is described.
