Ethyl-<4-nitro-phenyl>-α-methoxy-octylphosphonat, also known as EPN, is an organophosphorus compound that serves as an insecticide and acaricide. It is a colorless, oily liquid with a molecular formula of C14H24NO5P and a molecular weight of 317.32 g/mol. EPN works by inhibiting the enzyme acetylcholinesterase, which disrupts the nervous system of pests, leading to their paralysis and eventual death. It is effective against a wide range of insects, including aphids, mites, and beetles, and is used in agriculture and horticulture to protect crops from damage. However, due to its potential health risks and environmental concerns, its use has been restricted or banned in many countries.
The CAS Registry Mumber 1099-61-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,9 and 9 respectively; the second part has 2 digits, 6 and 1 respectively. Calculate Digit Verification of CAS Registry Number 1099-61: (6*1)+(5*0)+(4*9)+(3*9)+(2*6)+(1*1)=82 82 % 10 = 2 So 1099-61-2 is a valid CAS Registry Number.
