Disodium 6-amino-5-[(4-amino-2-sulphonatophenyl)azo]-4-hydroxynaphthalene-2-sulphonate is a water-soluble azo dye that exhibits a dark red to light purple color. It is known for its color-changing properties in the presence of different chemical agents, such as strong sulfuric acid and strong hydrochloric acid, which cause it to turn yellow-brown and red, respectively. Its water solution also changes color when mixed with sodium hydroxide, turning into a ruby red color.

5Check Digit Verification of cas no
The CAS Registry Mumber 6360-09-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,6 and 0 respectively; the second part has 2 digits, 0 and 9 respectively.Calculate Digit Verification of CAS Registry Number 6360-09:
(6*6)+(5*3)+(4*6)+(3*0)+(2*0)+(1*9)=84
84 % 10 = 4
So 6360-09-4 is a valid CAS Registry Number.
