Check Digit Verification of cas no

The CAS Registry Mumber 93725-04-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,7,2 and 5 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 93725-04:
(7*9)+(6*3)+(5*7)+(4*2)+(3*5)+(2*0)+(1*4)=143
143 % 10 = 3
So 93725-04-3 is a valid CAS Registry Number.

Cycloaddition d'ylures d'azomethine derives de la 3,4-dihydro-6,7-dimethoxy-3-methoxycarbonyl-isoquinoleine

Lakhlifi, Tahar,Sedqui, Ahmed,Laude, Bernard,An, Nguyen Dinh,Vebrel, Joel

, p. 1156 - 1160 (2007/10/02)

Three azomethine ylide precursors including the 3,4-dihydro-6,7-dimethoxyisoquinoline-3-carboxylate moiety were synthesized.The 1,3-dipolar species formed from these products react with activated dipolarophilic olefines leading diastereospecifically to derivatives of 4',5'-dimethoxy-1,2-benzo-4,7-imino-4-methoxycarbonyl-1-cycloheptene.Proton magnetic resonance data allowed the determination of the stereochemistry of the cycloadducts. Key words: cyclic azomethine ylide, azabicyclic compounds, stereochemistry.
