82-47-3 Usage

General Description

4-amino-5-hydroxynaphthalene-1,3-disulphonic acid is an organic compound that belongs to the family of naphthylamines and derivatives. 4-amino-5-hydroxynaphthalene-1,3-disulphonic acid is also known as H-acid and is widely used in the manufacturing of dyes due to its capacity to produce a broad spectrum of colors. It's composed of hydroxyl, sulfonyl, and amino functional groups attached to a naphthalene base. The chemical formula is C10H9NO7S2. While it has many industrial uses, it's important to note that improper handling and disposal of this substance may pose environmental risks due to its high toxicity.

Check Digit Verification of cas no

The CAS Registry Mumber 82-47-3 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 2 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 82-47:
(4*8)+(3*2)+(2*4)+(1*7)=53
53 % 10 = 3
So 82-47-3 is a valid CAS Registry Number.
