5-[[2-[(2-Amino-8-hydroxy-6-sulfo-1-naphthalenyl)azo]-4-sulfophenyl]sulfonyl]-2-hydroxybenzoic acid trisodium salt is a water-soluble dye that exhibits different colors depending on the pH and the presence of other chemicals. It is characterized by its brilliant blue color in its reduced form and red color in its oxidized form. It is also slightly soluble in ethanol, showing a magenta color, and turns orange-brown in concentrated sulfuric acid, turning pink upon dilution. The dye's aqueous solution turns red when concentrated hydrochloric acid is added and purple when concentrated sodium hydroxide solution is added.

4Check Digit Verification of cas no
The CAS Registry Mumber 6360-12-9 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, 1 and 2 respectively.Calculate Digit Verification of CAS Registry Number 6360-12:
(6*6)+(5*3)+(4*6)+(3*0)+(2*1)+(1*2)=79
79 % 10 = 9
So 6360-12-9 is a valid CAS Registry Number.
