7-chloro-2-(4-nitro-phenyl)-pyrano[3,4-e][1,3]oxazine-4,5-dione is a complex organic chemical compound with the molecular formula C13H6ClN2O5. It is characterized by a pyrano[3,4-e][1,3]oxazine core, which is a fused ring system consisting of a pyran (a six-membered oxygen-containing ring) and an oxazine (a six-membered nitrogen-containing ring). The compound features a 7-chloro substituent, which is a chlorine atom attached to the seventh carbon of the pyrano[3,4-e][1,3]oxazine ring, and a 4-nitro-phenyl group, which is a phenyl ring (a benzene ring) with a nitro group (-NO2) at the fourth position. The 4,5-dione part of the name indicates the presence of two carbonyl groups (C=O) at the fourth and fifth positions of the molecule. 7-chloro-2-(4-nitro-phenyl)-pyrano[3,4-e][1,3]oxazine-4,5-dione is likely to be found in research settings, particularly in the fields of medicinal chemistry and chemical synthesis, due to its potential applications in the development of new drugs or as a synthetic intermediate.
The CAS Registry Mumber 5725-73-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,2 and 5 respectively; the second part has 2 digits, 7 and 3 respectively. Calculate Digit Verification of CAS Registry Number 5725-73: (6*5)+(5*7)+(4*2)+(3*5)+(2*7)+(1*3)=105 105 % 10 = 5 So 5725-73-5 is a valid CAS Registry Number.
