3-[[4-Amino-9,10-dihydro-9,10-dioxo-3-(sodiosulfo)anthracen-1-yl]amino]benzoic acid ethyl ester is a complex organic compound with unique properties. It is characterized by its blue color and solubility in ethanol and soluble fiber element. However, it is insoluble in benzene, carbon tetrachloride, and pottery, making it particularly useful in specific applications. When treated with strong sulfuric acid, it exhibits a green light blue color, which turns into a red light blue solution when diluted, and eventually precipitates.

The CAS Registry Mumber 6424-88-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,2 and 4 respectively; the second part has 2 digits, 8 and 8 respectively.Calculate Digit Verification of CAS Registry Number 6424-88:
(6*6)+(5*4)+(4*2)+(3*4)+(2*8)+(1*8)=100
100 % 10 = 0
So 6424-88-0 is a valid CAS Registry Number.
