Phosphoric acid 4-(aminosulfonyl)phenyldiethyl ester, also known as fenthion, is an organophosphorus compound that serves as an insecticide and acaricide. It is a colorless to pale yellow liquid with a slight odor and is used to control a wide range of pests, including insects and mites, in agricultural and horticultural settings. Fenthion works by inhibiting the enzyme acetylcholinesterase, which disrupts the nervous system of the target pests, leading to their paralysis and eventual death. Due to its high toxicity, it is essential to handle fenthion with caution and follow proper safety measures to minimize risks to human health and the environment.

Check Digit Verification of cas no

The CAS Registry Mumber 1981-20-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,8 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1981-20:
(6*1)+(5*9)+(4*8)+(3*1)+(2*2)+(1*0)=90
90 % 10 = 0
So 1981-20-0 is a valid CAS Registry Number.
