4-Amino-2,5-dichlorobenzenesulfonic acid is a chemical compound with the molecular formula C6H5Cl2NO3S. It is a derivative of benzenesulfonic acid and is commonly used in organic synthesis and as an intermediate for the production of dyes and pharmaceuticals. The compound is a white crystalline solid that is soluble in water and has a strong acidic nature. It is a strong reducing agent and can react violently with oxidizing agents. Due to its potential health hazards and environmental impact, the handling and disposal of 4-Amino-2,5-dichlorobenzenesulfonic acid should be done with care and in accordance with regulations.
Check Digit Verification of cas no
The CAS Registry Mumber 88-50-6 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 88-50:
(4*8)+(3*8)+(2*5)+(1*0)=66
66 % 10 = 6
So 88-50-6 is a valid CAS Registry Number.
