Phosphorothioic acid O-[4-(aminosulfonyl)phenyl]O,O-diethyl ester, also known as ethion, is an organophosphorus compound widely used as an insecticide and acaricide. It is a colorless to pale yellow liquid with a chemical formula of C10H16NO5PS2. Ethion is effective against a broad spectrum of pests, including aphids, mites, and whiteflies, and is commonly applied in agriculture to protect crops such as cotton, fruits, and vegetables. The mode of action involves inhibiting acetylcholinesterase, an enzyme essential for nerve impulse transmission in insects, leading to their paralysis and death. Due to its potential health and environmental risks, ethion is classified as a restricted-use pesticide in some countries, and its use is regulated to minimize exposure and protect non-target organisms.

1902-25-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1902-25-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,0 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1902-25:
(6*1)+(5*9)+(4*0)+(3*2)+(2*2)+(1*5)=66
66 % 10 = 6
So 1902-25-6 is a valid CAS Registry Number.
