Check Digit Verification of cas no

The CAS Registry Mumber 54417-83-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,4,1 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 54417-83:
(7*5)+(6*4)+(5*4)+(4*1)+(3*7)+(2*8)+(1*3)=123
123 % 10 = 3
So 54417-83-3 is a valid CAS Registry Number.

Pulse Radiolysis of Arenediazonium Salts in Water/tert.-Butanol

Brede, O.,Mehnert, R.,Naumann, W.,Becker, H. G. O.

, p. 666 - 672 (2007/10/02)

The pulse radiolysis of benzenediazonium tetrafluoroborate and its p-NMe2, p-MeO, p-Me, p-Cl, p-COOEt, and p-CN derivatives was studied in water/tert.-butanol mixtures.Absorption spectra observed at wavelengths between 400 and 700 nm were attributed to the recombination products (tetrazadienes) Ar-N=N-N=N-Ar of arenediazo radicals Ar-N=N. which are generated by a diffusion-controlled reaction of the solvated electrons with the solute.The recombination of Ar-N=N. competes with an unimolecular decay of these radicals.According to an inhomogeneous initial distribution of Ar-N=N. the apparent rate of the recombination reaction is higher than the diffusion-controlled limit.For the unimolecular decay of Ar-N=N. rate constants between (1.8 and 330) * 105s-1 were calculated.The tetrazadienes decompose unimolecularly with rate constants from (0.3 to 17) * 105s-1. - The rate constants of the decay of the arenediazo radicals as well as of the decomposition of tetrazadienes exhibit good Hammet plots with almost identical reaction constants indicating similar paths of nitrogen elimination.
