Check Digit Verification of cas no

The CAS Registry Mumber 21919-29-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,1 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21919-29:
(7*2)+(6*1)+(5*9)+(4*1)+(3*9)+(2*2)+(1*9)=109
109 % 10 = 9
So 21919-29-9 is a valid CAS Registry Number.

The Structures of the fac and mer Isomers of Trichlorotrisiridium(III)

Robertson, Glen B.,Tucker, Paul A.

, p. 814 - 821 (1981)

The structure of the facial isomer of trichlorotrisiridium(III) has been determined, and that of the meridional isomer has been redetermined. fac-IIICl3(PMe2Ph)3>(1) crystallizes in space group Ia with a=16.198(2), b=14.923(2), c=22.024(2) Angstroem, β=96.37(2) deg, Z=8. mer-IIICl3(PMe2Ph)3>(2) crystallizes in space group P21/n with a=10.814(1), b=38.894(3), c=13.663(1) Angstroem, β=107.15(1) deg, Z=8.The structures were refined to R=0.025 and 0.031 .Metal-ligand distances in (1) are Ir-Cl 2.456(2)-2.468(2) Angstroem (trans to P) and Ir-P 2.285(2)-2.295(2) Angstroem (trans to Cl).Metal-ligand distances in (2) do not differ significantly from those reported earlier but are more precise and reveal the existence of small differences between chemically equivalent bonds due to inequivalence of intramolecular non-bonding interactions.Values from this experiment are: Ir-Cl 2.434(1)-2.439(1) Angstroem (trans to P) and 2.359(1)-2.368(1) Angstroem (trans to Cl), Ir-P 2.278(1)-2.282(1) Angstroem (trans to Cl) and 2.363(1)-2.384(1) Angstroem (trans to P).
