Tetraethyl-N''-phenylphosphorodiamidic chloride, also known as EPN, is a chemical compound with the formula C12H21Cl2NP. It is an organophosphorus compound that belongs to the class of phosphorodiamidic chlorides. EPN is a colorless, oily liquid with a pungent odor and is soluble in organic solvents. It is primarily used as an insecticide and acaricide, targeting a wide range of pests, including insects and mites. The compound works by inhibiting the activity of acetylcholinesterase, an enzyme essential for the proper functioning of the nervous system in insects. This inhibition leads to the accumulation of acetylcholine, causing overstimulation and ultimately paralysis and death of the target pests. Due to its high toxicity and potential environmental impact, the use of EPN has been restricted or banned in many countries.

3185-83-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3185-83-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,8 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3185-83:
(6*3)+(5*1)+(4*8)+(3*5)+(2*8)+(1*3)=89
89 % 10 = 9
So 3185-83-9 is a valid CAS Registry Number.
