102303-79-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 102303-79-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,3,0 and 3 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 102303-79:
(8*1)+(7*0)+(6*2)+(5*3)+(4*0)+(3*3)+(2*7)+(1*9)=67
67 % 10 = 7
So 102303-79-7 is a valid CAS Registry Number.

Condensation of 2-Nitrobenzaldehyde with Pyrazolin-5-ones. Structure of 4-(2'-Nitrobenzylidene)pyrazolin-5-ones and their Reductive Cyclization

Danel, A.,Tomasik, P.

, p. 1013 - 1017 (2007/10/02)

The condensation of 1-H-3-methyl-, 3-methyl-1-phenyl-, 1,3-diphenyl- and 1-methyl-3-phenyl-pyrazolin-5-ones with 2-nitrobenzaldehyde resulted in forming the corresponding 4-(2'-nitrobenzylidene)pyrazolin-5-ones.In some cases these products were assisted b

New Aspects in the Reaction of Azomethines with Cyclic CH-Acidic Compounds

Hennig, Lothar,Alva-Astudillo, Mario,Mann, Gerhard,Kappe, Thomas

, p. 571 - 580 (2007/10/02)

Treatment of substituted benzylidene anilines 1a - f with cyclic CH-acidic compounds 2a - m in ethanol at room temperature yields in addition/elimination reactions the corresponding arylidene derivatives 4 and the 2:1 adducts 5.The addition products 3, which are formed as intermediates, could not be isolated in any case.The donor/acceptor effect of the substituents on the benzylidene moiety influences to a significant extent the reactivity towards the azomethine carbon. Keywords.Azomethine; CH-Acidic compound; Addition/elimination reaction.
