66671-82-7 Usage

General Description

2,5-Diaminoanisole sulfate is a chemical compound commonly used in hair dyes and colors. It is an organic compound with the molecular formula C7H11N3O4S and is a derivative of aniline. This chemical is known for its ability to provide permanent color to hair and is often found in oxidative hair dye formulations. However, it has been identified as a potential allergen and skin irritant, and has been restricted or banned in some countries due to safety concerns. In addition to its use in hair dyes, 2,5-Diaminoanisole sulfate is also used in the production of certain pharmaceuticals and as a chemical intermediate in the synthesis of other compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 66671-82-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,6,7 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 66671-82:
(7*6)+(6*6)+(5*6)+(4*7)+(3*1)+(2*8)+(1*2)=157
157 % 10 = 7
So 66671-82-7 is a valid CAS Registry Number.
