80310-36-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 80310-36-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,3,1 and 0 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 80310-36:
(7*8)+(6*0)+(5*3)+(4*1)+(3*0)+(2*3)+(1*6)=87
87 % 10 = 7
So 80310-36-7 is a valid CAS Registry Number.

Diels-Alder Reaction: 1,4-Cycloaddition of N-Aryl-maleimides to Alkylidene- and Arylidene-fluorenones and Synthesis of Some New Fluoranthene Derivatives

Abdou, Sadek E.,Habashy, Adiba,Aziz, Gamil,Khalifa, Fathy

, p. 755 - 758 (2007/10/02)

The 1,4-cycloaddition of different N-arylmaleimides (IIa-f) to alkylidene- and arylidene-fluorenones (Ia-c) leads to the formation of the diadducts, 7-substituted-5-aryl-4,6-dioxo-4H-3,3a,5,6,6a,7,10b-octahydrofluoranthenopyrrole-endo(3,10b)-N-arylpyrrolidino-2',5'-diones (IIIa-r).The fully aromatized fluoranthene derivatives (Va-i) have also been synthesised either by boiling III in nitrobenzene or by reacting the bromo-derivatives (V) with appropriate II.Reduction of III using LAH gives VIII.The structures of the isolated products have been confirmed by elemental analyses, molecular weight determination and spectroscopic data.
