5-[[4'-[(6-Amino-1-hydroxy-3-sulfo-2-naphtyl)azo]-1,1'-biphenyl-4-yl]azo]-2-hydroxybenzoic acid disodium salt is a water-soluble azo dye that exhibits red coloration. It is soluble in ethanol for an orange hue and insoluble in other organic solvents. The dye undergoes color changes in the presence of acids and bases, turning purple in strong sulfuric acid and brown when diluted. It also shows light fastness, acid resistance, and alkali resistance properties.

3-4Check Digit Verification of cas no
The CAS Registry Mumber 6253-15-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,5 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.Calculate Digit Verification of CAS Registry Number 6253-15:
(6*6)+(5*2)+(4*5)+(3*3)+(2*1)+(1*5)=82
82 % 10 = 2
So 6253-15-2 is a valid CAS Registry Number.
