50392-39-7 Usage

General Description

4-Amino-2,5-dichlorophenol is a chemical compound with the molecular formula C6H5Cl2NO. It is a white to light yellow crystalline solid that is classified as an aromatic amine. This chemical is commonly used as an ingredient in the production of pharmaceuticals, dyes, and pigments. It is also used as a corrosion inhibitor and in the synthesis of other organic compounds. 4-Amino-2,5-dichlorophenol is considered to have low toxicity, but prolonged exposure can cause skin and eye irritation. It is important to handle and store this chemical with care to minimize any potential health hazards.

Check Digit Verification of cas no

The CAS Registry Mumber 50392-39-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,3,9 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 50392-39:
(7*5)+(6*0)+(5*3)+(4*9)+(3*2)+(2*3)+(1*9)=107
107 % 10 = 7
So 50392-39-7 is a valid CAS Registry Number.
