It is a derivative of pyrazolone, a class of organic compounds with a five-membered ring containing two nitrogen atoms and a ketone group. 2-(3-aminophenyl)-2,4-dihydro-5-methyl-3H-pyrazol-3-one has a 3-aminophenyl group attached to the carbon-2 position of the pyrazolone ring, as well as a methyl group at the carbon-5 position. It is commonly used as a building block in the synthesis of pharmaceuticals, agrochemicals, and other organic compounds due to its versatile reactivity and potential biological activity. Additionally, it has been studied for its potential as an anti-inflammatory and analgesic agent, as well as for its antimicrobial and antiviral properties.
Check Digit Verification of cas no
The CAS Registry Mumber 90-32-4 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 0 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 90-32:
(4*9)+(3*0)+(2*3)+(1*2)=44
44 % 10 = 4
So 90-32-4 is a valid CAS Registry Number.
