O-ethyl O-(4-nitrophenyl) (4-methylphenyl)phosphonothioate, also known as EPN, is an organophosphorus compound that was once widely used as an insecticide. It is a colorless, oily liquid with a chemical formula of C10H12NO4PS. EPN works by inhibiting the enzyme acetylcholinesterase, which is essential for the proper functioning of the nervous system in insects. This inhibition leads to the accumulation of acetylcholine, causing overstimulation and ultimately death in the target pests. However, due to its high toxicity to humans and potential environmental risks, its use has been largely discontinued in many countries. It is important to handle this chemical with extreme caution and to be aware of its restrictions and regulations in different regions.

4268-95-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4268-95-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,6 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4268-95:
(6*4)+(5*2)+(4*6)+(3*8)+(2*9)+(1*5)=105
105 % 10 = 5
So 4268-95-5 is a valid CAS Registry Number.
