Check Digit Verification of cas no

The CAS Registry Mumber 19095-23-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,0,9 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 19095-23:
(7*1)+(6*9)+(5*0)+(4*9)+(3*5)+(2*2)+(1*3)=119
119 % 10 = 9
So 19095-23-9 is a valid CAS Registry Number.

METHOF FOR PRODUCING HYDRIDOSILANES

-

Paragraph 0063-0067, (2019/11/22)

The invention relates to a method for producing hydridosilanes, in which siloxanes containing Si—H groups are reacted in the presence of a cationic Si(II) compound as a catalyst.

Effect of catalyst structure on the reaction of α-methylstyrene with 1,1,3,3-tetramethyldisiloxane

De Vekki,Skvortsov

body text, p. 762 - 777 (2009/09/26)

Reaction of α-methylstyrene with 1,1,3,3-tetramethyldisiloxane in the presence of the complexes of platinum(II), palladium(II) and rhodium(I) is explored. It is established that in the presence of platinum catalyst predominantly occurs hydrosilylation of α-methylstyrene leading to formation of β-adduct, on palladium catalysts proceeds reduction of α-methylstyrene, on rhodium catalysts both the processes take place. In the reaction mixture proceeds disproportion and dehydrocondensation of 1,1,3,3-tetramethyldisiloxane that leads to formation of long chain linear and cyclic siloxanes of general formula HMe2Si(OSiMe2) n H and (-OSiMe2-)m (n = 2-6, m = 3-7), respectively. Platinum catalysts promotes formation of linear siloxanes, while both rhodium and palladium catalysts afford linear and cyclic siloxanes as well. Structure of intermediate metallocomplexes is studied.

A Convenient Synthesis of α,ω-Difunctionalized Linear Dimethylsiloxanes with Definite Chain Lengths

Yoshino, Koji,Kawamata, Akira,Uchida, Hiroaki,Kabe, Yoshio

, p. 2133 - 2136 (2007/10/02)

α,ω-Difunctionalized linear dimethylsiloxanes with definite chain lengths are conveniently prepared by the inorganic-solid-catalyzed ring cleavage of cyclodimethylsiloxanes with dimethylchlorosilane and water under very mild conditions.
