Ethyl-amidophosphoric acid diphenyl ester, also known as O,O-diphenyl-N-(2-hydroxyethyl) phosphoramidate, is an organophosphorus compound with the chemical formula C14H16NO3P. It is a colorless liquid with a molecular weight of 281.25 g/mol. ethyl-amidophosphoric acid diphenyl ester is primarily used as a precursor in the synthesis of various pesticides, particularly organophosphorus insecticides, due to its ability to form stable phosphorus-nitrogen bonds. It is also employed as a reagent in the preparation of other organophosphorus compounds. Ethyl-amidophosphoric acid diphenyl ester is known for its high reactivity and is often used in the formation of esters and amides. However, it is important to handle this chemical with care due to its potential toxicity and reactivity.

5756-02-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5756-02-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,5 and 6 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5756-02:
(6*5)+(5*7)+(4*5)+(3*6)+(2*0)+(1*2)=105
105 % 10 = 5
So 5756-02-5 is a valid CAS Registry Number.
