"(Rh(4,7-Ph2-phen)(cod))ClO4" is a rhodium-based organometallic complex, where Rh represents the rhodium metal center. The complex features a 4,7-diphenyl-1,10-phenanthroline ligand, which is a bidentate nitrogen donor ligand known for its strong field and chelating properties. The cod ligand, short for 1,5-cyclooctadiene, is a diene ligand that can bind to the metal center in a η4 (four electron) fashion, providing stability to the complex. The ClO4- ion is a perchlorate counterion, which balances the overall charge of the complex. (Rh(4,7-Ph2-phen)(cod))ClO4 is of interest in the field of homogeneous catalysis, particularly for reactions involving the activation of small molecules like hydrogen or carbon monoxide, due to the unique electronic and steric properties conferred by the ligands.
The CAS Registry Mumber 80263-28-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,2,6 and 3 respectively; the second part has 2 digits, 2 and 8 respectively. Calculate Digit Verification of CAS Registry Number 80263-28: (7*8)+(6*0)+(5*2)+(4*6)+(3*3)+(2*2)+(1*8)=111 111 % 10 = 1 So 80263-28-1 is a valid CAS Registry Number.
