4553-89-3 Usage
Description
Disodium 4,4'-[[2,4-dihydroxy-5-(hydroxymethyl)-1,3-phenylene]bis(azo)]bisnaphthalene-1-sulphonate, also known as Chocolate Brown HT, is a synthetic organic compound used as a food colorant. It is characterized by its red light brown color and is soluble in water, producing a brown solution. When treated with strong sulfuric acid, it turns red purple, and upon dilution, it precipitates as chocolate brown. The solution then turns brown upon precipitation. Additionally, when sodium hydroxide solution is added, the product turns red.

Check Digit Verification of cas no
The CAS Registry Mumber 4553-89-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,5 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4553-89:
(6*4)+(5*5)+(4*5)+(3*3)+(2*8)+(1*9)=103
103 % 10 = 3
So 4553-89-3 is a valid CAS Registry Number.
