3-(4-bromo-phenyl)-4-thioxo-3,4-dihydro-benzo[e][1,3]oxazin-2-one is a complex organic chemical compound with the molecular formula C13H8BrNO2S. It features a benzo[e][1,3]oxazine core structure, which is a fused ring system consisting of a benzene ring attached to an oxazine ring. The compound is characterized by the presence of a 4-bromo-phenyl group, which is a phenyl ring substituted with a bromine atom at the 4-position. Additionally, it has a 4-thioxo group, indicating a sulfur atom double-bonded to the carbonyl carbon, and a 3,4-dihydro moiety, which implies the presence of two hydrogen atoms attached to the carbon atoms in the 3 and 4 positions of the benzo[e][1,3]oxazine ring. 3-(4-bromo-phenyl)-4-thioxo-3,4-dihydro-benzo[e][1,3]oxazin-2-one may be of interest in medicinal chemistry or as a precursor in the synthesis of other complex molecules.
The CAS Registry Mumber 7134-64-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,3 and 4 respectively; the second part has 2 digits, 6 and 4 respectively. Calculate Digit Verification of CAS Registry Number 7134-64: (6*7)+(5*1)+(4*3)+(3*4)+(2*6)+(1*4)=87 87 % 10 = 7 So 7134-64-7 is a valid CAS Registry Number.
