934561-62-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 934561-62-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,4,5,6 and 1 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 934561-62:
(8*9)+(7*3)+(6*4)+(5*5)+(4*6)+(3*1)+(2*6)+(1*2)=183
183 % 10 = 3
So 934561-62-3 is a valid CAS Registry Number.

Tris(biphenyl-4-yl)silyl-endcapped polyynes
Chalifoux, Wesley A.,Ferguson, Michael J.,Tykwinski, Rik R.
, p. 1001 - 1006 (2008/03/12)
The use of tris(biphenyl-4-yl)silyl (TBPS) as a large protecting group for polyynes has been investigated. The basic building block, TBPS-C≡C-TMS (1), is synthesized in a new "one-pot" reaction through the sequential addition of lithiated nucleophiles to
