Check Digit Verification of cas no
The CAS Registry Mumber 4702-72-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,0 and 2 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4702-72:
(6*4)+(5*7)+(4*0)+(3*2)+(2*7)+(1*2)=81
81 % 10 = 1
So 4702-72-1 is a valid CAS Registry Number.

Oxidation of Arylhydrazones by Thallium(III) Acetate - A Kinetic Analysis of Structural Effect on the Oxidation

The kinetics of oxidation of the phenylhydrazones of several substituted benzaldehydes by Tl(III) has been studied in aqueous acetic acid in the presence of initially added sodium chloride (0.05M).The reaction exhibits a first order dependence on and and is retarded by added sodium chloride and sodium acetate.The reaction is accelerated by electron-releasing substituents in the benzaldehyde moiety while electron-withdrawing substituents retard the reaction.The reaction data obey Hammett relationship with ρ = -1.62.Electron-withdrawing groups in the phenylhydrazine moiety also reduce the reaction rate (ρ = -2.66).The major product of the reaction is the cis-monohydrazone of benzil.
