The chemical compound in question is a rhodium-based complex with the formula [RhH(CO)((CH3)3C)2PCH2CH2CHCH2CH2P(C(CH3)3)2]+ and its counterion is [B(C6H5)4]-. This complex features a rhodium atom at its center, bonded to a hydride (H-), a carbon monoxide (CO) ligand, and two phosphorus-containing ligands. The phosphorus ligands are connected to the rhodium through a series of carbon atoms, with one ligand having a direct P-Rh bond and the other being part of a larger alkyl chain. The counterion, [B(C6H5)4]-, is a tetraarylborate anion, which balances the positive charge of the rhodium complex. [RhH(CO)(((CH3)3C)2PCH2CH2CHCH2CH2P(C(CH3)3)2)](1+)*[B(C6H5)4](1-) is likely to be used in homogeneous catalysis, particularly in reactions involving hydrogenation or hydroformylation, due to the presence of a rhodium center and the ability of the phosphorus ligands to stabilize and direct the metal's activity.

Check Digit Verification of cas no

The CAS Registry Mumber 81817-92-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,8,1 and 7 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 81817-92:
(7*8)+(6*1)+(5*8)+(4*1)+(3*7)+(2*9)+(1*2)=147
147 % 10 = 7
So 81817-92-7 is a valid CAS Registry Number.
