Check Digit Verification of cas no

The CAS Registry Mumber 81373-19-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,3,7 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81373-19:
(7*8)+(6*1)+(5*3)+(4*7)+(3*3)+(2*1)+(1*9)=125
125 % 10 = 5
So 81373-19-5 is a valid CAS Registry Number.

The one-electron reduction potential of 4-substituted phenoxyl radicals in water

Lind,Shen,Eriksen,Merényi

, p. 479 - 482 (2007/10/02)

By means of pulse radiolysis the one-electron reduction potentials of twelve 4-substituted phenoxy radicals have been determined. The main reference used was the ClO2./ClO2- couple. By combining the redox potentials of phenoxyl radicals with the aqueous acidities of phenols the bond strength of the phenolic O-H bond was calculated. These values were found to be in good agreement with O-H bond dissociation enthalpies measured in the gas phase.
