Dithiophosphoric acid O,O'-diethyl ester S-[(isopropyl-phenyl-carbamoyl)-methyl] ester, also known as ethoprophos, is an organophosphorus compound that serves as an agricultural insecticide and acaricide. It is a colorless liquid with a slight odor and is used to control a variety of pests, including aphids, mites, and whiteflies, on various crops such as cotton, fruits, and vegetables. Ethoprophos works by inhibiting the enzyme acetylcholinesterase in the nervous system of insects, leading to their paralysis and eventual death. It is considered a broad-spectrum pesticide and is known for its quick knockdown effect on pests. However, due to its potential health risks and environmental concerns, its use is regulated in many countries, and alternative, less harmful pesticides are often preferred.
The CAS Registry Mumber 3277-96-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,7 and 7 respectively; the second part has 2 digits, 9 and 6 respectively. Calculate Digit Verification of CAS Registry Number 3277-96: (6*3)+(5*2)+(4*7)+(3*7)+(2*9)+(1*6)=101 101 % 10 = 1 So 3277-96-1 is a valid CAS Registry Number.
