Di-carbamoyl-phenylphosphin, also known as 1,3-di-carbamoyl-5-phenyl-1,3,2λ5-phosphole, is a chemical compound with the molecular formula C9H10N2O2P. It is a derivative of phosphole, a heterocyclic compound containing a phosphorus atom in a five-membered ring. The structure of di-carbamoyl-phenylphosphin features two carbamoyl groups (-NH-CO-NH2) attached to the phosphorus atom, and a phenyl group (C6H5) connected to one of the carbon atoms in the ring. Di-carbamoyl-phenylphosphin is of interest in the field of organophosphorus chemistry, as it exhibits unique reactivity and properties due to the presence of both carbamoyl and phenyl groups. Di-carbamoyl-phenylphosphin can be synthesized through various methods, such as the reaction of dichlorophosphine with phenyl isocyanate, and has potential applications in the development of new materials and pharmaceuticals.
The CAS Registry Mumber 5773-28-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,7 and 3 respectively; the second part has 2 digits, 2 and 8 respectively. Calculate Digit Verification of CAS Registry Number 5773-28: (6*5)+(5*7)+(4*7)+(3*3)+(2*2)+(1*8)=114 114 % 10 = 4 So 5773-28-4 is a valid CAS Registry Number.
