3-phenyl-isoxazole-4,5-dione 4-[(4-nitro-phenyl)-hydrazone] is a complex organic compound with the molecular formula C16H10N4O4. It is derived from the isoxazole-4,5-dione class of chemicals, which are characterized by a five-membered heterocyclic ring containing an oxygen atom and a nitrogen atom. In this specific compound, a phenyl group is attached to the isoxazole ring, and a 4-nitro-phenyl-hydrazone group is connected to the carbonyl carbon of the isoxazole-4,5-dione. The 4-nitro-phenyl-hydrazone group consists of a phenyl ring with a nitro group at the para position and a hydrazone linkage to the isoxazole core. 3-phenyl-isoxazole-4,5-dione 4-[(4-nitro-phenyl)-hydrazone] is of interest in chemical research due to its potential applications in the synthesis of various pharmaceuticals and agrochemicals, as well as its unique chemical properties.
The CAS Registry Mumber 4865-98-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,6 and 5 respectively; the second part has 2 digits, 9 and 8 respectively. Calculate Digit Verification of CAS Registry Number 4865-98: (6*4)+(5*8)+(4*6)+(3*5)+(2*9)+(1*8)=129 129 % 10 = 9 So 4865-98-9 is a valid CAS Registry Number.
