Check Digit Verification of cas no
The CAS Registry Mumber 12128-81-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,1,2 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 12128-81:
(7*1)+(6*2)+(5*1)+(4*2)+(3*8)+(2*8)+(1*1)=73
73 % 10 = 3
So 12128-81-3 is a valid CAS Registry Number.

Synthesis and Structures of Low-Valent Tungsten Complexes Bearing Chiral Oxazoline-Derived Ligands
Lloyd-Jones, Guy C.,Pfaltz, Andreas
, p. 361 - 367 (2007/10/02)
The synthesis of low-valent tungsten (0 and II) complexes bearing chiral bidentate phosphino-oxazoline or bisoxazoline ligands is described.The structures of four of the complexes have been determined by single crystal X-ray analyses.Tungsten(II)-allyl complexes of the type (PN = phosphino-oxazoline) are fluxional in solution, but can be crystallized as single diastereoisomers.The complex , which also crystallizes as a single diastereomer, is readily oxidized in solution and solid state, in stark contrast to analogous compounds bearing four carbonyl ligands or (NN = bisoxazoline) which were found to be stable. functions as a highly enantioselective catalyst in allylic substitution reactions with dimethyl sodiomalonate, whereas complexes of the type (Z = H, Ph; X = Cl, Br) failed to yield allylic alkylation products. - Keywords: Chiral Tungsten Complexes, Phosphino-oxazoline Ligands, Bisoxazoline Ligands, Tungsten Allyl Complexes, Asymmetric Catalysis
