109022-49-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109022-49-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,0,2 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 109022-49:
(8*1)+(7*0)+(6*9)+(5*0)+(4*2)+(3*2)+(2*4)+(1*9)=93
93 % 10 = 3
So 109022-49-3 is a valid CAS Registry Number.

CYCLOADDITION OF STABLE DISILENE TO TERMINAL ACETYLENES
de Young, Douglas J.,West, Robert
, p. 883 - 884 (2007/10/02)
Tetramesityldisilene and trans-1,2-di-t-butyl-1,2-dimesityldisilene (3) react with various 1-alkynes to give air-stable disilacyclobutenes.The cycloaddition of 3 to alkynes produces equal amounts of both stereoisomers, consistent with a stepwise mechanism
