Check Digit Verification of cas no

The CAS Registry Mumber 83187-18-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,1,8 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 83187-18:
(7*8)+(6*3)+(5*1)+(4*8)+(3*7)+(2*1)+(1*8)=142
142 % 10 = 2
So 83187-18-2 is a valid CAS Registry Number.

REACTIONS DE CYCLOADDITION DIPOLAIRE-1,3 DES THIAZOLONES MESOIONIQUES AVEC DES COMPOSES ETHYLENIQUES-1. ETUDE DES PROBLEMES DE STEREOCHIMIE POSES PAR L'APPROCHE DIPOLE-DIPOLAROPHILE

Baudy, M.,Robert, A.,Guimon, G.

, p. 1241 - 1252 (1982)

The stereochemistry of cycloadducts obtained through the reaction of mesoionic thiazolones with ethylenic dipolarophiles is established.The dipole-dipolarophile approach is discussed in terms of interactions between the frontier orbitals.When the dipolarophile is acrylonitrile we note the importance of the destabilising interaction between the HOMO orbitals of the reactants.When the dipolarophile is vinyl ethyl ether we show that the interaction LUMO dipole-HOMO dipolarophile can be dominating.
