31731-67-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 31731-67-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,7,3 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 31731-67:
(7*3)+(6*1)+(5*7)+(4*3)+(3*1)+(2*6)+(1*7)=96
96 % 10 = 6
So 31731-67-6 is a valid CAS Registry Number.

Dehydrogenative double silylation of acetylenes with bis(hydrosilane) compounds
Tanaka, M.,Uchimaru, Y.
, p. 667 - 675 (2007/10/02)
Dehydrogenative double silylation of acetylenes with o-bis(dimethylsilyl)benzene was catalyzed by Pt(CH2=CH2)(PPh3)2 under mild conditions to give benzo-1,4-disilacyclohexa-2,5-dienes(1,4-benzodisilines) in 50-100percent yields.Depending on the structure
