1221795-65-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1221795-65-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,7,9 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1221795-65:
(9*1)+(8*2)+(7*2)+(6*1)+(5*7)+(4*9)+(3*5)+(2*6)+(1*5)=148
148 % 10 = 8
So 1221795-65-8 is a valid CAS Registry Number.

Isocyano analogues of [Co(CO)4]n: AA tetraisocyanide of cobalt isolated in three states of charge

Margulieux, Grant W.,Weidemann, Nils,Lacy, David C.,Moore, Curtis E.,Rheingold, Arnold L.,Figueroa, Joshua S.

, p. 5033 - 5035 (2010/06/14)

The encumbering m-terphenyl isocyanide ligand, CNArMes2 (Mes = 2,4,6-Me3C6H2), is used to stabilize homoleptic tetraisocyanide complexes of cobalt in the 1?, 0, and 1+ charge state. Most importantly, these complexes serve as isolable analogues of the binary carbonyl complexes [Co(CO)4]?, Co(CO)4, and [Co(CO) 4]+. Sodium amalgam reduction of CoCl2 in the presence of CNArMes2 provides the salt Na[Co(CNArMes2) 4], which can be oxidized with 1 equiv of ferrocenium triflate (FcOTf) to the neutral complex, Co(CNArMes2)4. X-ray diffraction, FTIR spectroscopy, and low-temperature EPR spectroscopy reveal that Co(CNArMes2)4 modulates between D2d- and C2v-symmetric forms. DFT calculations are used to rationalize this structural modulation in terms of thermal access to low-energy b 2-symmetric C?Co?C bending modes. Treatment of Na[Co(CNAr Mes2)4] with 2 equiv of FcOTf, followed by addition of Na[BArF4], provides the salt [Co(CNArMes2) 4]BArF4, which contains a diamagnetic, square planar monovalent cobalt center. The molecular and electronic structures of [Co(CNArMes2)4]BArF4 are compared and contrasted to the reported properties of the carbonyl cation, [Co(CO) 4]+.
