Check Digit Verification of cas no

The CAS Registry Mumber 854938-75-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,4,9,3 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 854938-75:
(8*8)+(7*5)+(6*4)+(5*9)+(4*3)+(3*8)+(2*7)+(1*5)=223
223 % 10 = 3
So 854938-75-3 is a valid CAS Registry Number.

Synthesis of a new class of compounds containing a Ln-O-Al moiety has been accomplished by the reaction of LAIOH(Me) (L = HC(CMeNAr)2, Ar = 2,6-iPr2C6H3) with a series of Cp3Ln compounds. The terminal AI-OH group shows selective reactivity, and the complexes Cp2Ln(THF)-O-AIL(Me) (Ln = Yb, 1; Er, 2; Dy, 3), Cp 2Yb-O-AIL(Me) (4), and Cp3Ln(μ-OH)AIL(Me) (Ln = Er, 5; Dy, 6; Sm, 7) were obtained. This allows further insight into the proton exchange process, and two different mechanisms, intermolecular and intramolecular elimination of CpH, are proposed under different conditions. Complexes 1-4, 6, and 7 have been characterized by X-ray structural analyses which reveals a Ln-O-Al or Ln(μ-OH)Al core in these complexes. The obtuse Ln-O-Al angles fall in the range 151.9-169.8°. The reaction of 1 or 4 with Me3SnF in toluene under refluxing conditions unexpectedly yielded the compounds [Cp2Yb-(μ-OSnMe3)]2 (8) and LAI(Me)F (9). Reactions of LAIOH(Me) with the mono- and dicyclopentadienyl complexes LYbCp(Cl) (10) and LYbCp2 (11) supported by the bulky β-diketiminate ligand were unsuccessful. However, the reaction of LAI(OH)Me with LYbN(SiMe3)2Cl (12) containing a labile Yb-N bond leads to the formation of LYbCl-O-AIL(Me) (13) under elimination of HN(SiMe 3)2. Furthermore, complexes 1, 3, 4, and 6 exhibit good catalytic activity for the polymerization of ε-caprolactone.
