Description

8-Hydroxy-7-[[4'-[(2-hydroxy-1-naphtyl)azo]-1,1'-biphenyl-4-yl]azo]-1,3,6-naphthalenetrisulfonic acid trisodium salt is a complex organic compound that exhibits unique color properties when dissolved in various solvents and under different conditions. It is characterized by its blue-purple color in water, which turns purple when the strong sulfuric acid solution is diluted. In nitric acid, the color shifts to yellow and then red. When a dye solution of this compound is mixed with a 10% sodium hydroxide solution, it produces a strong red light purple color.

Check Digit Verification of cas no

The CAS Registry Mumber 6426-67-1 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 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6426-67:
(6*6)+(5*4)+(4*2)+(3*6)+(2*6)+(1*7)=101
101 % 10 = 1
So 6426-67-1 is a valid CAS Registry Number.
