3-(3,4-dichloro-phenyl)-2,4-dioxo-3,4-dihydro-2H-benzo[e][1,3]oxazine-6-carboxylic acid methyl ester is a complex organic compound with the molecular formula C15H9Cl2NO5. It is characterized by a benzene ring with two chlorine atoms at the 3 and 4 positions, a 1,3-oxazine ring fused to the benzene ring, and a carboxylic acid group at the 6 position, which is esterified with a methyl group. 3-(3,4-dichloro-phenyl)-2,4-dioxo-3,4-dihydro-2H-benzo[e][1,3]oxazine-6-carboxylic acid methyl ester is a derivative of benzoxazine and is known for its potential applications in the synthesis of pharmaceuticals and agrochemicals due to its structural diversity and reactivity. The presence of the dichloro-phenyl group and the esterified carboxylic acid suggest that it may have specific biological activities or could be a precursor in the synthesis of more complex molecules.
The CAS Registry Mumber 2053-11-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,5 and 3 respectively; the second part has 2 digits, 1 and 1 respectively. Calculate Digit Verification of CAS Registry Number 2053-11: (6*2)+(5*0)+(4*5)+(3*3)+(2*1)+(1*1)=44 44 % 10 = 4 So 2053-11-4 is a valid CAS Registry Number.
