Check Digit Verification of cas no

The CAS Registry Mumber 83431-45-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,4,3 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 83431-45:
(7*8)+(6*3)+(5*4)+(4*3)+(3*1)+(2*4)+(1*5)=122
122 % 10 = 2
So 83431-45-2 is a valid CAS Registry Number.

1,3-DIPOLAR CYCLOADDITIONS OF YLIDE OF 5-NITRO-2-FURFURYLPYRIDINIUM BROMIDE IN INDOLIZINE SYNTHESIS

Stetinova, Jarmila,Dandarova, Miloslava,Kovac, Jaroslav,Mesarosova, Darina,Lesko, Jan

, p. 1738 - 1745 (2007/10/02)

Substituted 3-(5-nitro-2-furyl)indolizines III-X were synthesized by 1,3-dipolar cycloaddition reaction of the ylide II, generated from 5-nitro-2-furfurylpyridinium bromide (I), with acrylonitrile, ethyl acrylate, diethyl maleate, benzalacetophenone, ethyl 3-(5-nitro-2-furyl)acrylate, (5-nitro-2-furfurylidene)acetophenone, β-nitrostyrene and dimethyl acetylenedicarboxylate.The structure of these products is discussed on the basis of their 1H NMR and mass spectra.
