Check Digit Verification of cas no

The CAS Registry Mumber 1380681-04-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,0,6,8 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1380681-04:
(9*1)+(8*3)+(7*8)+(6*0)+(5*6)+(4*8)+(3*1)+(2*0)+(1*4)=158
158 % 10 = 8
So 1380681-04-8 is a valid CAS Registry Number.

An efficient method for the synthesis of symmetrical disiloxanes from alkoxysilanes using Meerwein's reagent

Jorapur, Yogesh R.,Shimada, Toyoshi

, p. 1633 - 1638 (2012/08/07)

We report here a new and efficient route to symmetrical disiloxanes from their corresponding alkoxysilanes using Meerwein's reagent as mediator and potassium carbonate as additive under mild reaction conditions in acetonitrile. Our methodology is very simple, economic, and high yielding. We have also proposed a reaction mechanism with the plausible silyloxonium intermediates. Georg Thieme Verlag Stuttgart · New York.
