1-oxo-2,3,6-(D-penicillaminato-N,S,O)-4,5-(D-penicillaminato-N,S)technetium(V) is a complex chemical compound that consists of a technetium atom in the +5 oxidation state, which is coordinated to two D-penicillamine ligands. D-penicillamine is a chelating agent derived from the amino acid cysteine, and it forms stable complexes with metal ions. In 1-oxo-2,3,6-(D-penicillaminato-N,S,O)-4,5-(D-penicillaminato-N,S)technetium(V), one D-penicillamine ligand is attached to the technetium atom through its nitrogen, sulfur, and oxygen atoms, while the other D-penicillamine ligand is coordinated through its nitrogen and sulfur atoms. The compound also features a 1-oxo group, which is a carbonyl group (C=O) bonded to the technetium atom. This complex is of interest in the field of nuclear medicine, particularly for imaging and therapeutic applications, due to its ability to bind to specific biological targets and its radiopharmaceutical properties.
The CAS Registry Mumber 80572-91-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,5,7 and 2 respectively; the second part has 2 digits, 9 and 1 respectively. Calculate Digit Verification of CAS Registry Number 80572-91: (7*8)+(6*0)+(5*5)+(4*7)+(3*2)+(2*9)+(1*1)=134 134 % 10 = 4 So 80572-91-4 is a valid CAS Registry Number.
