Check Digit Verification of cas no

The CAS Registry Mumber 57928-54-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,9,2 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 57928-54:
(7*5)+(6*7)+(5*9)+(4*2)+(3*8)+(2*5)+(1*4)=168
168 % 10 = 8
So 57928-54-8 is a valid CAS Registry Number.

Kinetic Investigation on the Hydrogen Transfer from Dihydropyridines to Hydrazyls

Abou-Elenien, G.,Rieser, J.,Ismail, N.,Wallenfels, K.

, p. 391 - 394 (2007/10/02)

The results of a kinetic study on the hydrogen transfer between different dihydropyridines and mono-, bis- and trishydrazyls of the tricyanobenzene series are described.The reactions have been found to obey in all cases a second-order law.The influences of solvent medium, redox-potentials of the reactants and temperature on the rates of reactions have been investigated. - Keywords: Dihydropyridines, Hydrazyls, Hydrogen Transfer, Kinetics
