7-Hydroxy-8-[[2-methyl-4-[[6,8-bis(sodiosulfo)-2-naphthalenyl]azo]phenyl]azo]naphthalene-1,3-disulfonic acid disodium salt is a water-soluble organic compound that exhibits colorful red-blue light. It is soluble in water, producing a red color, but not soluble in alcohol. In strong sulfuric acid, it appears dark blue, and when diluted, it turns into a red product. When added to a water solution, the compound changes from red to wine red upon the addition of strong hydrochloric acid, and turns dark brown when thick sodium hydroxide solution is added.

4Check Digit Verification of cas no
The CAS Registry Mumber 6226-88-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,2 and 6 respectively; the second part has 2 digits, 8 and 8 respectively.Calculate Digit Verification of CAS Registry Number 6226-88:
(6*6)+(5*2)+(4*2)+(3*6)+(2*8)+(1*8)=96
96 % 10 = 6
So 6226-88-6 is a valid CAS Registry Number.
