Check Digit Verification of cas no

The CAS Registry Mumber 31787-05-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,7,8 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 31787-05:
(7*3)+(6*1)+(5*7)+(4*8)+(3*7)+(2*0)+(1*5)=120
120 % 10 = 0
So 31787-05-0 is a valid CAS Registry Number.

Absorption Spectra of Monoaza and Diaza Unsymmetrical Trimethine Cyanines Derived from Substituted Benzothiazoles

Shatapathy, D.,Misra, P. K.

, p. 84 - 85 (2007/10/02)

Effect of substituents on the absorption spectra of monoaza (Ia) and diaza (Ib) unsymmetrical cyanines derived from 6-substituted benzothiazoles has been studied.A simple and new model has been proposed which excellently correlates the longest wavelength electronic absorption maxima of the dyes linearly with the Hammett substituent constants.
