Acetohydroxamic acid (AHA) is a chemical compound with the formula C2H5NO2. It is a derivative of hydroxamic acid, where the hydrogen atom is replaced by an acetate group. AHA is a white crystalline solid that is soluble in water and has a slightly bitter taste. It is primarily used as a chelating agent, particularly in the extraction of metal ions from aqueous solutions. In the pharmaceutical industry, AHA is used as an intermediate in the synthesis of various drugs, including antibiotics and anticoagulants. Additionally, it has been studied for its potential use as a herbicide and a treatment for certain parasitic infections. The compound is also of interest in chemical research due to its ability to form complexes with metal ions, which can be useful in understanding the coordination chemistry of these metals.

Check Digit Verification of cas no

The CAS Registry Mumber 4202-72-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,0 and 2 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4202-72:
(6*4)+(5*2)+(4*0)+(3*2)+(2*7)+(1*2)=56
56 % 10 = 6
So 4202-72-6 is a valid CAS Registry Number.
