The chemical compound "(C2H5O)4Ta(N(C6H5)COOC2H5)" is a complex organometallic compound consisting of a tantalum (Ta) atom at its core. The tantalum is surrounded by four ethoxide ligands, each represented by (C2H5O), which are alkoxide groups derived from ethanol. Additionally, the compound features a ligand with a nitrogen atom bonded to a phenyl group (C6H5) and an ethyl carboxylate group (COOC2H5). This nitrogen-containing ligand is known as a Schiff base, which is formed by the condensation of an amine with an aldehyde or ketone. The Schiff base ligand in (C2H5O)4Ta(N(C6H5)COOC2H5) is likely to be chelating, meaning it wraps around the metal center, forming multiple bonds with it. The overall structure suggests that (C2H5O)4Ta(N(C6H5)COOC2H5) could be used in various applications, such as a catalyst or a precursor in the synthesis of other tantalum-containing materials.
The CAS Registry Mumber 65845-30-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,8,4 and 5 respectively; the second part has 2 digits, 3 and 0 respectively. Calculate Digit Verification of CAS Registry Number 65845-30: (7*6)+(6*5)+(5*8)+(4*4)+(3*5)+(2*3)+(1*0)=149 149 % 10 = 9 So 65845-30-9 is a valid CAS Registry Number.
