Check Digit Verification of cas no

The CAS Registry Mumber 68040-30-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,0,4 and 0 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 68040-30:
(7*6)+(6*8)+(5*0)+(4*4)+(3*0)+(2*3)+(1*0)=112
112 % 10 = 2
So 68040-30-2 is a valid CAS Registry Number.

Anodic Pyridination of 2-Hydroxy-3-methoxy-5-methylbenzaldehyde and its Schiff's Base Derivatives

Ohmori, Hidenobu,Matsumoto, Akiteru,Masui, Masaichiro

, p. 347 - 357 (2007/10/02)

Anodic oxidation of substituted phenols, 2-hydroxy-3-methoxy-5-methylbenzaldehyde (1) and its Schiff's base derivatives (2) in acetonitrile containing an excess of pyridine gave pyridinated phenols.Pyridination occured at the methyl group of the hydroxybenzaldehyde (1) and the Schiff's base (2g) derived from p-nitroaniline, while for the other Schiff's base derivatives of (1) studied the pyridinium group was on the ring meta to the hydroxy and ortho to the imino group.The pyridination process was investigated by cyclic voltammetry and controlled potential and constant current electrolysis of (1), (2), and related phenols including 2-hydroxy-3-methoxybenzaldehyde Schiff's bases (4).Two different routes are suggested for pyridination, a process involving a phenoxonium ion and one involving a quinone methide.Under the conditions of controlled potential electrolysis, ring pyridination proceeds through the phenoxonium ion route and side-chain pyridination through the quinone methide route.The role of the imino group in the anodic oxidation of the phenolic Schiff's bases (2) and (4) is discussed.The principal mode is suggested to be catalysis of the dimerisation of the corresponding cation radicals by accepting the proton of the hydroxy-group intramolecularly to remove the positive charge from the reaction centre.
