Check Digit Verification of cas no

The CAS Registry Mumber 171863-30-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,8,6 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 171863-30:
(8*1)+(7*7)+(6*1)+(5*8)+(4*6)+(3*3)+(2*3)+(1*0)=142
142 % 10 = 2
So 171863-30-2 is a valid CAS Registry Number.

First Synthesis of a Binuclear [MnII(bipy)-FeIII(porphyrin)] Complex: Spectroscopic Characterization and First Evidence of Reversible Formation of Manganese(III) as Manganese Peroxidase

Policar, Clotilde,Artaud, Isabelle,Mansuy, Daniel

, p. 210 - 216 (2008/10/09)

A [(P)FeIII-MnII] bimetallic complex, mimicking the active site of manganese peroxidase, has been synthesized. A modified highly fluorinated porphyrin, 5,10,15-tris(pentafluorophenyl)-20-(o-aminophenyl)porphyrin, has been used to introduce, through a short spacer linked to the amino function, a manganese auxiliary ligand, 6-aminomethyl-2,2′-bipyridine. Two successive metalations by FeCl2 and MnCl2 afforded the [(P)FeIII-MnII] bimetallic complex that has been characterized by elemental analysis and FAB+ mass spectrometry. X-band EPR spectroscopy and magnetic susceptibility measurements were in agreement with two high spin Fe(III) and Mn(II) centers without magnetic exchange interaction. Moreover, there is no higher intermolecular association through μ-chloro bridging as observed by EPR with a simpler chloromanganese complex, Mn(bipy)2Cl2, at high concentration. Addition of pentafluoroiodosobenzene in methanol at 0 °C led to the progressive and complete disappearance of the EPR Mn(II) signals, that were recovered after addition of a phenol. This result is consistent with Mn(III) formation. This production of Mn(III) requires the presence of the iron porphyrin and is proposed to occur through the intermediate formation of a Fe(IV) dimethoxide species which can be related to the oxidation of Mn(II) catalyzed by manganese peroxidase compound II.
