ChEBI: A quinoline derivative with a 1,3-dioxoindan-2-yl substituent at C-2.

Check Digit Verification of cas no

The CAS Registry Mumber 83-08-9 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 83-08:
(4*8)+(3*3)+(2*0)+(1*8)=49
49 % 10 = 9
So 83-08-9 is a valid CAS Registry Number.

QUINOPHTHALONE COMPOUND AND COMPOSITION CONTAINING THE SAME

-

Paragraph 0050; 0051, (2018/11/27)

PROBLEM TO BE SOLVED: To provide a novel quinophthalone compound that has excellent clarity and color development, and has excellent solubility in a specific solvent. SOLUTION: The present invention provides an ammonium salt type quinophthalone compound represented by formula (1). (R1-R4 are H or a C1-15 alkyl group; R5 is H or a hydroxy group; R6, R7, R9 and R10 are H; R8 is H or a C1-4 alkyl group; Ar1 is a phthalone group or a naphthalone group, having one -SO3- group in the entire structure).

β-Diceto enamines heterocycliques: 1. Indanediones-1,3 substituees en 2 par un heterocycle azote

Ploquin, J.,Sparfel, L.,Baut, G. Le,Floc'h, R.,Letourneux, Y.

, p. 961 - 973 (2007/10/02)

The condensation of methylated N-heterocycles and especially monomethyl- and polymethylpyridines on phthalic anhydrides leads to 2-aryl-1,3-indanediones.The 3-alkylidenylphthalides formed in an intermediary state have been isolated.The influence of solvents and temperature on the velocity and yield of formation of 2-(2- and 4-pyridyl)-1,3-indandiones has been studied.The ir and nmr spectra confirm that these compounds exist under a β-diketoenamine form resonating with a betaine form.
