Thiophosphorsaeure-O-<2-phenylmercapto>-aethylester-S-phenylester-diaethylamid, also known as O-(2-phenylmercaptoethyl)-S-phenyl ethylphosphorothioate diethylamide, is a complex organic compound with the chemical formula C20H26NO3PS2. Thiophosphorsaeure-O-<2-phenylmercapto>-aethylester-S-phenylester-diaethylamid is a derivative of phosphorothioic acid, featuring a phenylmercaptoethyl group and a phenyl ethyl ester, both connected to the phosphorus atom. It is characterized by its two ester groups, one being a phenyl ester and the other an ethyl ester, and a diethylamide group. This chemical is primarily used as a pesticide, specifically as an insecticide, due to its ability to disrupt the nervous system of insects. It is important to handle such chemicals with care due to their potential toxicity and environmental impact.
The CAS Registry Mumber 3238-83-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,3 and 8 respectively; the second part has 2 digits, 8 and 3 respectively. Calculate Digit Verification of CAS Registry Number 3238-83: (6*3)+(5*2)+(4*3)+(3*8)+(2*8)+(1*3)=83 83 % 10 = 3 So 3238-83-3 is a valid CAS Registry Number.
