Check Digit Verification of cas no

The CAS Registry Mumber 20103-09-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,1,0 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20103-09:
(7*2)+(6*0)+(5*1)+(4*0)+(3*3)+(2*0)+(1*9)=37
37 % 10 = 7
So 20103-09-7 is a valid CAS Registry Number.

ESR-Spectroscopic Investigations on the Radical Cations of p-Phenylene Diamines and Related Compounds. The Determination of the Various Spin Polarisation Parameters

Grampp, Guenter,Stiegler, Guenter

, p. 185 - 200 (2007/10/02)

The ESR-spectra of the radical cations of various p-phenylenediamines and related compounds were measured.The coupling constants were determined by use of specifically deuterated compounds, calculation of the autocorrelation function and spectra simulation.The calculation of spin densities were carried out using the Hueckel method and McLachlans's method (POL-2) modified for radical cations.After adjustment of the nitrogen perturbation parameters hN(NR2) to the protonic splitings it is possible to determine the QX-values from the calculated nitrogen spin densities and the measured coupling constants.On the basis of these calculations the spin polarisation parameters QX of nitrogen and protons in NH2 and NMe2 groups were determined by means of the McConnell and Karplus-Fraenkel equations. - Keywords: ESR-spectroscopy / p-Phenylenediamines / Spin polarisation parameters
