Check Digit Verification of cas no

The CAS Registry Mumber 206561-65-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,6,5,6 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 206561-65:
(8*2)+(7*0)+(6*6)+(5*5)+(4*6)+(3*1)+(2*6)+(1*5)=121
121 % 10 = 1
So 206561-65-1 is a valid CAS Registry Number.

A half-sandwich perfluoroorganoytterbium(II) complex from a simple redox transmetalation/ligand exchange synthesis

Deacon, Glen B.,Forsyth, Craig M.

, p. 1349 - 1352 (2008/10/08)

The unique, half-sandwich perfluoroaryl-ytterbium(II) complex [Yb(C5Me5)(C6F5)(THF)3 ] (1) was synthesized in one step from Yb metal, HgPh(C6F5) and HC5Me5. A report on the successful synthesis and structure of the half-sandwich organoytterbium(II) complex by redox-transmetalation/ligand-exchange reaction is presented. Extrapolation to a wide range of novel organolanthanoid(II) complexes is envisaged.
