Tetrasodium 5,5'-[vinylenebis[(3-sulphonato-4,1-phenylene)azo]]bis(salicylate) is a synthetic azo dye characterized by its dark red to light yellow or orange color. It is soluble in water, displaying a yellow-orange hue, and slightly soluble in alcohol. The dye exhibits various color changes when exposed to different chemical environments, such as turning red to light purple in strong sulfuric acid and dark brown or black in dilute conditions. In nitric acid solution, it appears light yellow with gray precipitation. When mixed with strong hydrochloric acid, the dye solution turns dark brown with precipitation, and upon the addition of thick sodium hydroxide solution, it turns red.

The CAS Registry Mumber 6459-82-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,5 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.Calculate Digit Verification of CAS Registry Number 6459-82:
(6*6)+(5*4)+(4*5)+(3*9)+(2*8)+(1*2)=121
121 % 10 = 1
So 6459-82-1 is a valid CAS Registry Number.
