119771-49-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 119771-49-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,7,7 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 119771-49:
(8*1)+(7*1)+(6*9)+(5*7)+(4*7)+(3*1)+(2*4)+(1*9)=152
152 % 10 = 2
So 119771-49-2 is a valid CAS Registry Number.

Synthesis of Spiro Indolin-2-one Derivatives

El-Ahl, Abdel Asis S.,Afeefy, Hussein,Metwally, Mohamed Abbas

, p. 201 - 222 (2007/10/02)

The reactions of active methylene compounds and hydrazine with (2-oxoindolin-3-ylidene)-malononitrile and -acetophenone in ethanol/piperidine have been studied.Both substances gave Michael-type adducts followed by cyclization.The structures of the products were determined from the results of elemental analysis, IR, 1H-NMR and mass spectra.

Syntheses with Nitriles, LXXXII. - On Spiro and Indene-propellanes - Adducts of 2-(Dicyanomethylene)-1,3-indandione with 1,3-Dicarbonyl Compounds

Dworczak, Renate,Sterk, Heinz,Kratky, Christoph,Junek, Hans

, p. 1323 - 1328 (2007/10/02)

The reactivity of 2-(dicyanomethylene)-1,3-indandione (1) towards 1,3-dicarbonyl compounds depends strongly on the nature of the CH acidic component.While the reaction with dimedone yields a spiro (2), indene-propellanes (3) are formed with acetoacetic esters.Adducts of acetylacetone and benzoylacetic acid ethyl ester to 1 have been identified as spiro- (4).The propellane structure 3 is proven by X-ray analysis.Adducts 6 of CH acidic components with 3-(dicyanomethylene)-2-indolones 5 are used for reference measurements. - Key Words: Nitriles / Spiro compounds / Propellanes / Indan derivatives / Cycloaddition
