Flammability and Explosibility
Highlyflammable
Check Digit Verification of cas no
The CAS Registry Mumber 1719-58-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,1 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1719-58:
(6*1)+(5*7)+(4*1)+(3*9)+(2*5)+(1*8)=90
90 % 10 = 0
So 1719-58-0 is a valid CAS Registry Number.

Paragraph 0039; 0040, (2019/02/19)
The invention belongs to the technical field of organic synthesis, and particularly relates to a synthesis method for dimethylvinylchlorosilane. Antimony butter SbCl3 is taken as a catalyst, dimethyldichlorosilance Me2SiCl2 is taken as a raw material, and the antimony butter SbCl3 and the dimethyldichlorosilance Me2SiCl2 react with vinylmagnesium bromide or vinylmagnesium chloride to undergo Grignard reaction; the antimony butter SbCl3 which performs a key function as the catalyst is added to enable the yield of the dimethyldichlorosilance Me2ViSiCl to be greatly improved to be 80% or more (91% is highest) from the yield which does not exceed 15% according to the report in an original literature; when the comparison reaction of the catalyst antimony butter SbCl3 is not used, the yield of the dimethylvinylchlorosilane Me2ViSiCl is only 32.8%.
