Tetrasodium 3,3'-[(3,3'-dimethoxy[1,1'-biphenyl]-4,4'-diyl)bis(azo)]bis[4,5-dihydroxynaphthalene-2,7-disulphonate] is a blue solid dye that exhibits unique color properties and chemical resistance. It is soluble in water as a dark blue color and has adequate solubility in alcohol. The dye solution changes color when exposed to different chemical environments, such as turning greenish-blue in strong sulfuric acid and reddish-blue upon dilution. Additionally, it displays dark blue color when mixed with strong hydrochloric acid and turns violet-black when combined with a concentrated sodium hydroxide solution.

Check Digit Verification of cas no

The CAS Registry Mumber 4198-19-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,9 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4198-19:
(6*4)+(5*1)+(4*9)+(3*8)+(2*1)+(1*9)=100
100 % 10 = 0
So 4198-19-0 is a valid CAS Registry Number.
