Check Digit Verification of cas no

The CAS Registry Mumber 146073-68-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,0,7 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 146073-68:
(8*1)+(7*4)+(6*6)+(5*0)+(4*7)+(3*3)+(2*6)+(1*8)=129
129 % 10 = 9
So 146073-68-9 is a valid CAS Registry Number.

Alkylation of Pyridine-3,5-dicarboxamide and Pyridine-3,5-dicarbonitriles by Radical Substitution

Kanomata, Nobuhiro,Nagahara, Hisashi,Tada, Masaru

, p. 1567 - 1571 (2007/10/02)

Structural modification of NAD(P) model compounds, N,N,N',N'-tetramethylpyridine-3,5-dicarboxamide (1), pyridine-3,5-dicarbonitrile (2), and 4-methylpyridine-3,5-dicarbonitrile (3), have been explored by the reaction with alkyl radicals such as the 1-adamantyl, tert-butyl, and isopropyl radicals.The alkyl substitutions of compounds 1, 2, and 3 with 1-adamantyl and the tert-butyl radical gave both 2-mono- and 2,6-disubstitution products, whereas the reaction of compound 2 with the isopropyl radical gave 2-mono 6c, 2,4-di 7c, 2,6-di 8c, and 2,4,6-trisubstitution 9c products.
