S-ethyl O,O-dimethyl phosphorodithioate, also known as ethoprophos, is an organophosphorus compound widely used as an insecticide and acaricide. It is a colorless to pale yellow liquid with a garlic-like odor and has the chemical formula C5H13O2PS2. Ethoprophos works by inhibiting the enzyme acetylcholinesterase, which disrupts the nervous system of insects and mites, leading to their paralysis and eventual death. It is effective against a broad range of pests, including aphids, whiteflies, and spider mites, and is commonly used in agriculture to protect crops such as cotton, fruits, and vegetables. However, due to its high toxicity to humans and potential environmental risks, its use is regulated in many countries, and alternative, less harmful pesticides are often preferred.

3347-21-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3347-21-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,4 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.Calculate Digit Verification of CAS Registry Number 3347-21:
(6*3)+(5*3)+(4*4)+(3*7)+(2*2)+(1*1)=75
75 % 10 = 5
So 3347-21-5 is a valid CAS Registry Number.
