Check Digit Verification of cas no

The CAS Registry Mumber 71155-99-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,1,5 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 71155-99:
(7*7)+(6*1)+(5*1)+(4*5)+(3*5)+(2*9)+(1*9)=122
122 % 10 = 2
So 71155-99-2 is a valid CAS Registry Number.

Properties of chlorinated dihydroxybenzenes - components of pulp bleaching effluents

Smith, Terrence J.,Wearne, Ross H.,Wallis, Adrian F. A.

, p. 1555 - 1560 (2007/10/03)

Gas chromatography and mass spectrometry data are given for the chlorodihydroxybenzenes which are components of wood pulp bleaching effluents and biologically-treated effluents, and are proposed intermediates in the chlorination of humic acids. The chlorohydroxybenzenes include the nine chlorocatechols, the six chlorohydroquinones and the seven known chlororesorcinols. The 22 chlorinated compounds were generally well separated on a phenyl methyl silicone column with the exception of three dichloro compounds. The chloro compounds with the same level of chlorine substitution were not able to be distinguished on the basis of their electron impact mass spectra.
