Check Digit Verification of cas no

The CAS Registry Mumber 35142-04-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,1,4 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 35142-04:
(7*3)+(6*5)+(5*1)+(4*4)+(3*2)+(2*0)+(1*4)=82
82 % 10 = 2
So 35142-04-2 is a valid CAS Registry Number.

Carbon-13 NMR Spectra of Some Phenanthrene Derivatives from Aristolochia indica and their Analogues

Achari, Basudeb,Bandyopadhyay, Soumitra,Chakravarty, Ajit K.,Pakrashi, Satyesh C.

, p. 741 - 746 (1984)

(13)C NMR spectra of compounds related to aristolochic acid and aristololactam, the constituents of Aristolochia indica, have been studied to determine the chemical shifts and coupling constants of polysubstituted phenanthrenes.Selective (1)H decoupling and long-range couplings were utilized for the assignments.Substituent-induced chemical shifts and also the effects on coupling constants could be deduced in some cases.Anion formation was found to be particularly helpful in the interpretation of the spectra of carboxylic compounds.Shift assignments of some structurally related compounds could also be made.
