4-Amino-5-hydroxy-3-[(4-nitrophenyl)azo]-6-[[4-(phenylazo)phenyl]azo]naphthalene-2,7-disulfonic acid disodium salt is a complex organic compound characterized by its dark blue to light green color. It is soluble in water, slightly soluble in ethanol and acetone, and hardly soluble in benzene. When treated with strong sulfuric acid, it exhibits a blue-ray green color, which remains green even when diluted. In an aqueous solution, the addition of concentrated sodium hydroxide solution results in a gray light blue color.

The CAS Registry Mumber 6487-06-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,8 and 7 respectively; the second part has 2 digits, 0 and 6 respectively.Calculate Digit Verification of CAS Registry Number 6487-06:
(6*6)+(5*4)+(4*8)+(3*7)+(2*0)+(1*6)=115
115 % 10 = 5
So 6487-06-5 is a valid CAS Registry Number.
