Disodium 5,5'-[thiobis(p-phenyleneazo)]disalicylate, also known as Orange II, is a synthetic azo dye commonly used in various applications due to its bright orange color. This water-soluble chemical compound is characterized by its molecular formula C18H10N4Na2O7S2 and has a molecular weight of 534.39 g/mol. It is widely employed in the textile, paper, and leather industries for dyeing purposes, as well as in analytical chemistry for the determination of metal ions. Orange II is known for its high solubility in water, which makes it an effective dye, but also raises concerns about its environmental impact due to potential release into water bodies. The compound's structure features two salicylate groups connected by a central thiobis(p-phenyleneazo) bridge, which contributes to its color and chemical properties.

6471-17-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6471-17-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,7 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6471-17:
(6*6)+(5*4)+(4*7)+(3*1)+(2*1)+(1*7)=96
96 % 10 = 6
So 6471-17-6 is a valid CAS Registry Number.
