O,O-diethyl S-(tetrahydrothiophen-3-yl) phosphorodithioate, also known as EPN, is an organophosphorus compound that was once widely used as an insecticide and acaricide. It is characterized by its chemical structure, which includes a phosphorus atom bonded to two ethyl groups and a sulfur atom connected to a tetrahydrothiophen-3-yl group. EPN was particularly effective against a variety of pests, including mosquitoes, flies, and mites. However, due to its high toxicity and potential environmental and health risks, its use has been restricted or banned in many countries. The compound's mode of action involves inhibiting the enzyme acetylcholinesterase, leading to the accumulation of acetylcholine in the nervous system of insects, which ultimately results in paralysis and death. Despite its effectiveness, concerns over its persistence in the environment, potential for bioaccumulation, and impact on non-target species have led to its phased-out use in favor of safer alternatives.

6554-82-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6554-82-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,5 and 4 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6554-82:
(6*6)+(5*5)+(4*5)+(3*4)+(2*8)+(1*2)=111
111 % 10 = 1
So 6554-82-1 is a valid CAS Registry Number.
