Check Digit Verification of cas no
The CAS Registry Mumber 3248-05-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,4 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3248-05:
(6*3)+(5*2)+(4*4)+(3*8)+(2*0)+(1*5)=73
73 % 10 = 3
So 3248-05-3 is a valid CAS Registry Number.

Carbon-hydrogen bond breaking and making in the open-shell singlet molecule Cp2Yb(4,7-Me2phen)
Nocton, Grgory,Booth, Corwin H.,Maron, Laurent,Ricard, Louis,Andersen, Richard A.
, p. 6819 - 6829 (2014)
The adducts formed between the 4,7-Me2-, 3,4,7,8-Me4-, and 3,4,5,6,7,8-Me6-phenanthroline ligands and Cp2Yb are shown to have open-shell singlet ground states by magnetic susceptibility and LIII-edge XANES spectroscopy. Variable-temperature XANES data show that two singlet states are occupied in each adduct that are fit to a Boltzmann distribution for which δH = 5.75 kJ mol-1 for the 4,7-Me2phen adduct. The results of a CASSCF calculation for the 4,7-Me2phen adduct indicates that three open-shell singlet states, SS1-SS3, lie 0.44, 0.06. and 0.02 eV, respectively, below the triplet state. These results are in dramatic contrast to those acquired for the phenanthroline and 5,6-Me2phen adducts, which are ground state triplets (J. Am. Chem. Soc. 2014, 136, 8626). A model that accounts for these differences is traced to the relative energies of the LUMO and LUMO+1 orbitals that depend on the position the methyl group occupies in the phenanthroline ligand. The model also accounts for the difference in reactivities of Cp2Yb(3,8-Me2phen) and Cp2Yb(4,7-Me2phen); the former forms a σ C-C bond between C(4)C(4′), and the latter undergoes C-H bond cleavage at the methyl group on C(4) and leads to two products that cocrystallize: Cp2Yb(4-(CH2),7-Mephen), which has lost a hydrogen atom, and Cp2Yb(4,7-Me2-4H-phen), which has gained a hydrogen atom.

Catalyst compositions and a process for polymerizing carbon monoxide and olefins
-
, (2008/06/13)
Carbon monoxide and at least one olefinically unsaturated organic compound may be polymerized by contacting the monomers in the presence of a catalyst which comprises a Group VIII metal compound of palladium, cobalt or nickel, a halide of tin or germanium, a nitrogen bidentate ligand and an organic oxidant. The polymers prepared are linear alternating polymers which consist of units with the formula STR1 where A is the residue of an alkenically unsaturated organic compound monomer.
