Check Digit Verification of cas no
The CAS Registry Mumber 18402-76-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,0 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 18402-76:
(7*1)+(6*8)+(5*4)+(4*0)+(3*2)+(2*7)+(1*6)=101
101 % 10 = 1
So 18402-76-1 is a valid CAS Registry Number.

Lanthanocene (Ln = PrIII, YbIII) chlorides involving tetramethyldisiloxane-interlinked cyclopentadienyl ligands
Graeper, Jens,Fischer, R. Dieter,Paolucci, Gino
, p. 87 - 96 (1994)
Two new lanthanocenophanes PrIIICl*THF>x (2; x=1 or 2) and YbIIICl>2 (3), were made from LnCl3 (Ln=Pr or Yb) and K2 in THF.The 1H NMR spectra of THF-d8 solutions of paramagnetic 2 (at +35 to -25 deg C) and 3 (at 8 (at > 10 deg C), respectively, display somewhat less complex 1H NMR spectra consistent with a virtually symmetrical position of the Me2SiOSiMe2 unit with respect to the cent-Ln-cent' plane (cent = C5H4Si centroid).A low temperature (-100 deg C) single-crystal X-ray study of 3 has confirmed the presence of centrosymmetric, Cl-bridged dimers in which the molecular configuration of the mononuclear YbIIICl2 units correspond to that of the previously described complex IVCl2> (1).The high-resolution mass spectrum of 3 displays several signals from dinuclear fragments, the B/E-linked scans of which suggest, inter alia, intramolecular reorientation of at least one O(Me2SiC5H4)2 ligand from the chelating into a metal-bridging position.Key words: Ytterbium; Praseodymium; Metallocenes; Lanthanides; Chiral metallocenophanes; Crystal structure
