Check Digit Verification of cas no
The CAS Registry Mumber 17029-21-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,0,2 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 17029-21:
(7*1)+(6*7)+(5*0)+(4*2)+(3*9)+(2*2)+(1*1)=89
89 % 10 = 9
So 17029-21-9 is a valid CAS Registry Number.

Solid state molecular structures of transition metal hexafluorides
Drews, Thomas,Supel, Joanna,Hagenbach, Adelheid,Seppelt, Konrad
, p. 3782 - 3788 (2008/10/09)
Single-crystal structure determinations of all nine transition metal hexafluorides (Mo, Tc, Ru, Rh, W, Re, Os, Ir, and Pt) at -140°C are presented. All compounds crystallize alike and have the same molecular structure. The bond length sequence rW-F ? rRe-F ? rOs-F Ir-F Pt-F is confirmed and paralleled by the sequence rMo-F ? rTc-F ? rRu-F Rh-F. Within the limits of precision, no systematic deviation from octahedral symmetry can be established. DFT and ab initio calculations predict octahedral structures for MoF6 and RhF6 and tetragonally distorted structures for ReF6 and RuF6. The energy barrier toward octahedral structures is only 2.5 kJ mol-1 in the two latter cases. Calculated electron affinities are in the sequence MoF6 6 6 6 with a value of 6.98 eV for the latter. O2 +RhF6- crystallized in an undisordered manner in P1, isostructural to the low-temperature form of O2 +AuF6-. RhF6- has a D4h, compressed octahedral structure, while AuF6 - is essentially octahedral. The absorption spectrum of TcF 6 and the 19F and 195NMR spectra of PtF 6 are presented.
