Ethylthiophosphonic acid O-ethyl O-(2,4-dichlorophenyl) ester, also known as EPN, is an organophosphorus compound with the chemical formula C6H8Cl2O3PS. It is a colorless, oily liquid with a garlic-like odor. EPN is a potent cholinesterase inhibitor, which means it disrupts the normal functioning of the nervous system by inhibiting the enzyme acetylcholinesterase, leading to the accumulation of acetylcholine and causing overstimulation of the nervous system. This chemical was historically used as an insecticide, particularly for controlling pests in agriculture. However, due to its high toxicity and potential for environmental contamination, its use has been restricted or banned in many countries. It is important to handle EPN with extreme caution due to its acute toxicity, which can lead to severe health effects in humans and animals, including respiratory failure and death.

1593-27-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1593-27-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,9 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1593-27:
(6*1)+(5*5)+(4*9)+(3*3)+(2*2)+(1*7)=87
87 % 10 = 7
So 1593-27-7 is a valid CAS Registry Number.
