"O,O-Diaethyl-N-<4-cyan-phenyl>-N'-phenyl-phosphorsaeure-amidin" is a complex organic compound with the chemical formula C20H20N3O2P. It is a phosphoramide derivative, characterized by the presence of a phosphorus atom bonded to two ethyl groups (O,O-diethyl), a 4-cyan-phenyl group, and a phenyl group. The cyan group (-CN) is attached to the 4-position of the phenyl ring, and the phenyl group is connected to the nitrogen atom of the phosphoramide moiety. O,O-Diaethyl-N-<4-cyan-phenyl>-N'-phenyl-phosphorsaeure-amidin is known for its potential applications in the synthesis of pesticides and other agrochemicals, particularly as a precursor in the production of certain insecticides. Its structure and properties make it a versatile building block in organic chemistry, although it requires careful handling due to its potential toxicity and reactivity.
The CAS Registry Mumber 5524-78-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,2 and 4 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 5524-78: (6*5)+(5*5)+(4*2)+(3*4)+(2*7)+(1*8)=97 97 % 10 = 7 So 5524-78-7 is a valid CAS Registry Number.
