3-[[2,5-Dimethyl-4-[(1-hydroxy-6-phenylamino-3-sodiosulfo-2-naphthalenyl)azo]phenyl]azo]naphthalene-1,5-disulfonic acid disodium salt is a bright purple azo dye that is soluble in water, alcohol, and strong sulfuric acid. It exhibits various color changes when interacting with different chemicals, such as turning red light purple in water, product red to blue light purple in alcohol, and blue in strong sulfuric acid. The dye solution also shows color changes when mixed with strong hydrochloric acid (purple) and sodium hydroxide solution (strong purplish red precipitate).

3Check Digit Verification of cas no
The CAS Registry Mumber 6227-11-8 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 7 respectively; the second part has 2 digits, 1 and 1 respectively.Calculate Digit Verification of CAS Registry Number 6227-11:
(6*6)+(5*2)+(4*2)+(3*7)+(2*1)+(1*1)=78
78 % 10 = 8
So 6227-11-8 is a valid CAS Registry Number.
