Check Digit Verification of cas no
The CAS Registry Mumber 1631-83-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,3 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1631-83:
(6*1)+(5*6)+(4*3)+(3*1)+(2*8)+(1*3)=70
70 % 10 = 0
So 1631-83-0 is a valid CAS Registry Number.

Hydrogenation of chlorosilanes by NaBH4
Ito, Masaki,Itazaki, Masumi,Abe, Takashi,Nakazawa, Hiroshi
, p. 1434 - 1436 (2016)
Hydrogenation of chlorosilane was achieved in acetonitrile using NaBH4, a safe and easy-to-handle reagent. This reaction converted Si-Cl portion(s) in organosilanes into Si-H portion(s) without hydrogenation of cyano, chloro, and aldehyde groups on an alkyl substituent of the Si reagents. In addition, the Si-Cl/Si-H exchange reaction was applicable to dichlorodisilane without Si-Si bond cleavage.
CATALYTIC REDUCTION OF HALOGENATED CARBOSILANES AND HALOGENATED CARBODISILANES

Paragraph 0070; 0071, (2021/04/02)
Selective reduction methods for halogenated carbosilanes and carbodisilanes are disclosed. More particularly, high yields of the desired carbosilanes and carbodisilanes are obtained by reduction of their halogenated counterparts using a reducing agent and tetrabutylphosphonium chloride (TBPC) as a catalyst.
Facile preparation of hydrochlorosilane by alkali metal halide catalyzed Si-H/Si-Cl redistribution reaction
Chen, Yi,Li, Yongming,Xu, Caihong
supporting information, (2020/09/21)
Various alkali metal halides were found to catalyze the Si-H/Si-Cl redistribution reaction in different polar solvents efficiently. The scope of silane substrate was studied using KF as catalyst and 18-crown-6 as cocatalyst in DMI. The alkali metal halides catalyzed redistribution system provides a useful method to prepare hydrochlorosilanes more facilely. A possible mechanism was proposed to explain the process.
