120927-53-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 120927-53-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,9,2 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 120927-53:
(8*1)+(7*2)+(6*0)+(5*9)+(4*2)+(3*7)+(2*5)+(1*3)=109
109 % 10 = 9
So 120927-53-9 is a valid CAS Registry Number.

Binuclear transition-metal complexes of cyclophanoid cyclopentadienone and cyclopentadienyl ligands

Jutzi, Peter,Siemeling, Ulrich,Müller, Achim,B?gge, Hartmut

, p. 1744 - 1750 (2008/10/08)

The double-layered cyclophanoid cyclopentadienone 2,3,10,11-tetraphenyltricyclo[12.2.1.1 9,12]octadeca-1,3,9,11-tetraene-17,18-dione (7) is obtained by aldol condensation of cyclotetradecane-1,8-dione (8) with 2 equiv of benzil (9). 7 (= L) reacts with Ni(COD)2, Fe2(CO)9, and Cp*Co(C2H4)2 to give the binuclear cyclopentadienone complexes (COD)Ni-L-Ni(COD) (11a), (CO)3Fe-L-Fe(CO)3 (11b), and Cp*Co-L-CoCp* (11c). 11a reacts with tetrafluoroboric acid and trifluoromethanesulfonic acid to yield the respective (hydroxycyclopentadienyl)nickel complexes [(COD)Ni-LH2-Ni(COD)]2+·2BF4- (14a) and [(COD)Ni-LH2-Ni(COD)]2+·2CF3SO 3- (14b); likewise, (tetracyclone)Ni(COD) (13a) reacts with tetrafluoroboric acid to give the mononuclear hydroxycyclopentadienyl complex [(Ph4CpOH)Ni]+BF4- (14e); 11a and 11c react with triethyloxonium tetrafluoroborate to afford the binuclear ethoxycyclopentadienyl complexes [(COD)Ni-LEt2-Ni(COD)]2+·2BF4 - (14c) and [Cp*Co-LEt2-CoCp*]2+·2BF 4- (14d). The electrochemical properties of the binuclear (cyclopentadienone)cobalt complex 11c and the binuclear (ethoxycyclopentadienyl)nickel complex 14c are examined; both complexes show interacting redox sites. X-ray structural investigations on 11a show an anti conformation of the two quasi-planar cyclopentadienone rings, the distance between them being approximately 410 pm; each nickel atom is bonded η4 to its cyclopentadienone moiety, the Ni-Ni distance being 805 pm; the whole molecule is centrosymmetric (crystal system monoclinic; space group C2/c; a = 2433.1 (10) pm, b = 1425.1 (6) pm, c = 1850.0 (7) pm, β = 97.83 (3)° Z = 4).
