Check Digit Verification of cas no

The CAS Registry Mumber 18304-82-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,3,0 and 4 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 18304-82:
(7*1)+(6*8)+(5*3)+(4*0)+(3*4)+(2*8)+(1*2)=100
100 % 10 = 0
So 18304-82-0 is a valid CAS Registry Number.

Reaction of organylchlorosilanes with dimethyl sulfoxide in the presence of octamethyltrisiloxane

Basenko,Gebel',Boyarkina,Voronkov

, p. 882 - 884 (2007/10/03)

Dichloro(methyl)(vinyl)silane reacts with DMSO in the presence of octamethyltrisiloxane to form cyclooligomethyl(vinyl)siloxanes(MeViSiO) n (n = 3-6). The reaction involves disproportionation of octamethyltrisiloxane into hexamethyldisiloxane and decamethyltetrasiloxane. Along with the latter two products, insertion products of methyl vinyl silanone into both permethyloligosiloxanes were identified. Alkyltrichlorosilanes RSiCl3 (R = Me, Et) react with DMSO in the presence of octamethyltrisiloxane to form cyclic oligoalkyltrichlorosiloxanes (RClSiO) m (m = 3-6).
