Acid Brown 119 is a dark brown powder that is soluble in water, producing a yellow light brown solution. When it encounters strong sulfuric acid, the solution turns yellow light brown, and a yellow brown precipitate forms upon dilution. The addition of strong hydrochloric acid to its water solution results in a yellow brown precipitate, while the addition of a concentrated sodium hydroxide solution yields a blue-ray red color.

Preparation
3-Aminobenzenesulfonic acid diazo, and Benzene-1,4-diamine coupling ; 4-Nitrobenzenamine diazo, Coupled with resorcinol; And then the double nitriding 2,4-Diaminobenzenesulfonic acid respectively with the above two single accidentally coupled nitrogen compounds.Check Digit Verification of cas no
The CAS Registry Mumber 69428-27-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,4,2 and 8 respectively; the second part has 2 digits, 2 and 7 respectively.Calculate Digit Verification of CAS Registry Number 69428-27:
(7*6)+(6*9)+(5*4)+(4*2)+(3*8)+(2*2)+(1*7)=159
159 % 10 = 9
So 69428-27-9 is a valid CAS Registry Number.
