Phosphorodithioic acid, S-[2-(ethylsulfinyl)ethyl] O,O-dimethyl ester, also known as ethoprophos, is an organophosphorus compound widely used as an agricultural insecticide. It is a colorless to pale yellow liquid with a chemical formula of C6H15O3PS2. Ethoprophos works by inhibiting the enzyme acetylcholinesterase in insects, leading to the accumulation of acetylcholine and causing paralysis and death. It is effective against a broad spectrum of pests, including aphids, mites, and whiteflies. However, due to its high toxicity to humans and potential environmental risks, its use has been restricted or banned in several countries. Ethoprophos is also known for its strong odor and potential to cause respiratory irritation.

Check Digit Verification of cas no

The CAS Registry Mumber 2703-37-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,0 and 3 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2703-37:
(6*2)+(5*7)+(4*0)+(3*3)+(2*3)+(1*7)=69
69 % 10 = 9
So 2703-37-9 is a valid CAS Registry Number.
