Check Digit Verification of cas no

The CAS Registry Mumber 138823-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,8,2 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 138823-91:
(8*1)+(7*3)+(6*8)+(5*8)+(4*2)+(3*3)+(2*9)+(1*1)=153
153 % 10 = 3
So 138823-91-3 is a valid CAS Registry Number.

Regio- and chemoselective addition of mixed copper, zinc benzylic organometallics to functionalized pyridinium salts: A facile synthesis of functionalized 4-benzylpyridines

Shing,Chia,Shiao,Chau

, p. 849 - 850 (1991)

2',3-Disubstituted 4-benzylpyridines 4 were synthesized in good yield by reaction of mixed copper, zinc benzylic organometallics 1 with 3-substituted 1-(ethoxycarbonyl)pyridinium chlorides 2 followed by sulfur oxidation under reflux in decalin.
