Check Digit Verification of cas no

The CAS Registry Mumber 104331-05-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,3,3 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 104331-05:
(8*1)+(7*0)+(6*4)+(5*3)+(4*3)+(3*1)+(2*0)+(1*5)=67
67 % 10 = 7
So 104331-05-7 is a valid CAS Registry Number.

DIASTEREOSPECIFICITE DE LA REACTION D'UN YLURE D'AZOMETHINE DERIVE DE LA 1-PHENYL-3-METHOXYCARBONYL-3,4-DIHYDRO-β-CARBOLINE SUR QUELQUES DIPOLAROPHILES ETHYLENIQUES

Lakhlifi, Takar,An, Nguyen Dinh,Schmitt, Gerard,Laude, Bernard,Mercier, Marie-France

, p. 169 - 176 (2007/10/02)

The synthesis of the 1-phenyl-3-methoxycarbonyl-3,4-dihydro-β-carboline was described.This compound is an azomethine ylid precursor which reacts diastereo-specifically with activated dipolarophilic olefines to yield cycloadducts involving at the same time, the β-carboline and the dehydro-nor-tropane moieties.The diastereochemistry of the 1,3-dipolar cycloaddition of cyclic azomethine ylids towards the endo rule was reinvestigated.
