Acid brown 16 (C.I. 17610) is a synthetic dye characterized by its brown color. It is soluble in water, displaying a brown hue, and slightly soluble in ethanol, also appearing brown. When it comes into contact with strong sulfuric acid, it turns red light purple, and when diluted, it takes on an olive color. In a water solution, the addition of strong hydrochloric acid results in olive-colored precipitation, while the addition of sodium hydroxide yields a wine-red color.

4Check Digit Verification of cas no
The CAS Registry Mumber 6222-58-8 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 2 respectively; the second part has 2 digits, 5 and 8 respectively.Calculate Digit Verification of CAS Registry Number 6222-58:
(6*6)+(5*2)+(4*2)+(3*2)+(2*5)+(1*8)=78
78 % 10 = 8
So 6222-58-8 is a valid CAS Registry Number.
