Dithiophosphoric acid O,O'-diethyl ester S-[(ethyl-phenyl-carbamoyl)-methyl] ester, also known as ethyl diethylcarbamoylmethyl phosphorodithioate, is a complex organic compound with the chemical formula C13H22NO3PS2. It is a colorless to pale yellow liquid with a pungent odor. Dithiophosphoric acid O,O'-diethyl ester S-[(ethyl-phenyl-carbamoyl)-methyl] ester is primarily used as an agricultural pesticide, specifically as a systemic insecticide and acaricide, targeting a wide range of pests such as aphids, mites, and whiteflies. It works by inhibiting the acetylcholinesterase enzyme in insects, leading to their paralysis and eventual death. Due to its potential toxicity and environmental impact, it is crucial to follow proper safety measures and regulations when handling and applying this chemical.
The CAS Registry Mumber 3277-98-3 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 8 respectively. Calculate Digit Verification of CAS Registry Number 3277-98: (6*3)+(5*2)+(4*7)+(3*7)+(2*9)+(1*8)=103 103 % 10 = 3 So 3277-98-3 is a valid CAS Registry Number.
