91-30-5 Usage
General Description
4-Aminodiphenyamine-2-sulfonic acid is an aromatic compound that consists of a central benzene ring with two amine groups and one sulfonic acid group attached to it. It is often used as a building block for the synthesis of a variety of dyes, pigments, and other organic compounds. This chemical is water-soluble and has the potential to be toxic to aquatic organisms. It is important to handle and dispose of 4-Aminodiphenyamine-2-sulfonic acid with caution to minimize environmental impact.
Check Digit Verification of cas no
The CAS Registry Mumber 91-30-5 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 1 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 91-30:
(4*9)+(3*1)+(2*3)+(1*0)=45
45 % 10 = 5
So 91-30-5 is a valid CAS Registry Number.
