O,O-Diethyl-N-(4-chlor-phenyl)-N'-p-tolyl-phosphorsaeure-amidin, also known as a phosphorothioate compound, is an organophosphorus compound characterized by its chemical structure containing a phosphorus atom bonded to two ethyl groups, a 4-chlorophenyl group, and a p-tolyl group. O,O-Diethyl-N-(4-chlor-phenyl)-N'-p-tolyl-phosphorsaeure-amidin is a type of pesticide, specifically a cholinesterase inhibitor, which works by disrupting the nervous system of pests. It is used in agriculture to control a variety of insects and is known for its effectiveness in protecting crops from damage. However, due to its potential environmental and health risks, its use is regulated in many countries, and there is ongoing research into safer alternatives.
The CAS Registry Mumber 3559-78-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,5 and 9 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 3559-78: (6*3)+(5*5)+(4*5)+(3*9)+(2*7)+(1*8)=112 112 % 10 = 2 So 3559-78-2 is a valid CAS Registry Number.
