Disodium 4-[[4-[[4-[[6-[(4-aminobenzoyl)amino]-1-hydroxy-3-sulphonato-2-naphthyl]azo]benzoyl]amino]phenyl]azo]-4,5-dihydro-5-oxo-1-phenyl-1H-pyrazole-3-carboxylate is a complex organic compound with a unique chemical structure. It is characterized by its red-orange brown color, which is soluble in water and slightly soluble in ethanol. disodium 4-[[4-[[4-[[6-[(4-aminobenzoyl)amino]-1-hydroxy-3-sulphonato-2-naphthyl]azo]benzoyl]amino]phenyl]azo]-4,5-dihydro-5-oxo-1-phenyl-1H-pyrazole-3-carboxylate exhibits a bright red color in strong sulfuric acid, which turns orange upon dilution and results in red-orange precipitation. When mixed with strong hydrochloric acid, the dye solution turns red with the formation of a precipitate. The addition of a thick sodium hydroxide solution results in an orange-brown color and the formation of a precipitate.

Check Digit Verification of cas no

The CAS Registry Mumber 6391-23-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,9 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6391-23:
(6*6)+(5*3)+(4*9)+(3*1)+(2*2)+(1*3)=97
97 % 10 = 7
So 6391-23-7 is a valid CAS Registry Number.
