Check Digit Verification of cas no
The CAS Registry Mumber 123568-21-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,5,6 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 123568-21:
(8*1)+(7*2)+(6*3)+(5*5)+(4*6)+(3*8)+(2*2)+(1*1)=118
118 % 10 = 8
So 123568-21-8 is a valid CAS Registry Number.

Palladium-Catalyzed Alkenylation and Alkynylation of Polyhaloarenes
Tao, Weijin,Nesbitt, Stephanie,Heck, Richard F.
, p. 63 - 69 (2007/10/02)
Alkenylation of several polyhaloarenes proceeded in low to moderate yields.Iodo groups could be reacted selectively in the presence of bromo groups; however, no more than two alkenyl groups could be introduced on contiguous, aromatic carbons.Alkynylation
