Check Digit Verification of cas no

The CAS Registry Mumber 20638-18-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,6,3 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20638-18:
(7*2)+(6*0)+(5*6)+(4*3)+(3*8)+(2*1)+(1*8)=90
90 % 10 = 0
So 20638-18-0 is a valid CAS Registry Number.

Silanol Compound, Composition, and Method for Producing Silanol Compound

-

Paragraph 0242; 0243, (2017/07/14)

The purpose of the present invention is to provide silanol compounds that can be used as raw materials of siloxane compounds and the like, and a composition of the silanol compounds, as well as to provide a production method that makes it possible to produce silanol compounds at excellent yield. A composition comprising 5 mass % to 100 mass % of a silanol compound represented by Formulas (A) to (C) can be prepared by devising to produce silanol compounds under water-free conditions, to produce silanol compounds in a solvent having the effect of suppressing the condensation of silanol compounds, and to perform other such processes, the composition being able to be used as a raw material or the like of siloxane compounds because the silanol compounds can be stably present in the resulting composition.
