Check Digit Verification of cas no

The CAS Registry Mumber 22161-91-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,6 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 22161-91:
(7*2)+(6*2)+(5*1)+(4*6)+(3*1)+(2*9)+(1*1)=77
77 % 10 = 7
So 22161-91-7 is a valid CAS Registry Number.

Highly selective palladium-catalyzed oxidative Csp2-Csp 3 cross-coupling of arylzinc and alkylindium reagents through double transmetallation

Jin, Liqun,Zhao, Yingsheng,Zhu, Lizheng,Zhang, Heng,Lei, Aiwen

supporting information; experimental part, p. 630 - 634 (2009/11/30)

Using desyl chloride (2-chloro-1,2-diphenylethanone) as the oxidant, the palladium-catalyzed reaction of arylzinc with alkylindium reagents occurred smoothly in a highly selective manner to afford the products in 57-90% yields. Preliminary kinetic data in
