N-acetyl-3,5-diiodo-O-phenyl-L-tyrosine ethyl ester is a complex organic compound with the molecular formula C20H20I2NO4. It is a derivative of L-tyrosine, an amino acid, where the hydroxyl group at the 3rd and 5th carbon positions is substituted with iodine atoms, and the nitrogen atom is acetylated. The phenyl group is attached to the oxygen atom of the tyrosine, and an ethyl ester group is present at the carboxylic acid end. N-acetyl-3,5-diiodo-O-phenyl-L-tyrosine ethyl ester is of interest in chemical and pharmaceutical research due to its potential applications in the synthesis of various pharmaceuticals and as a precursor in the preparation of contrast agents for medical imaging. Its unique structure with two iodine atoms makes it a candidate for applications where heavy atom effects are beneficial, such as in X-ray or CT imaging.
The CAS Registry Mumber 3072-53-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,7 and 2 respectively; the second part has 2 digits, 5 and 3 respectively. Calculate Digit Verification of CAS Registry Number 3072-53: (6*3)+(5*0)+(4*7)+(3*2)+(2*5)+(1*3)=65 65 % 10 = 5 So 3072-53-5 is a valid CAS Registry Number.
