Check Digit Verification of cas no
The CAS Registry Mumber 27988-77-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,9,8 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 27988-77:
(7*2)+(6*7)+(5*9)+(4*8)+(3*8)+(2*7)+(1*7)=178
178 % 10 = 8
So 27988-77-8 is a valid CAS Registry Number.

The title compounds have been prepared from amorphous Au2O3·x H2O (x = 1-3) and Ln2O3 (Ln = Nd, Sm, Eu) via solid state reaction under elevated oxygen pressure adding KOH as mineralizing agent. They crystallize in a new structure type (triclinic, P1, Z = 1, Sm3AuO6: a = 3.7272(2) A?, b = 5.6311(2) A?, c = 7.0734(3) A?, α = 90.32(2)°, β = 103.983(3)°, γ = 90.822(2)°, 125 powder intensities, Rp = 2.57%, Eu3AuO6: a = 3.7012(2) A?, b = 5.6134(2) A?, c = 7.0652(4) A?, α =90.838(3)°, β = 102.956(3)°, γ = 90.909(2)°, 122 powder intensities, Rp = 3.16%, Gd3AuO6: a = 3.6720(2) A?, b = 5.5977(2) A?, c = 7.0636(2) A?, α = 90.509(2)°, β = 102.889(3)°, γ = 91.068(2)°, 3424 reflections, R1 = 12.90%). The crystal structure was solved and refined from single crystal data of Gd3AuO6. The structures of Sm3AuO6 and Eu3AuO6 were refined from powder diffraction data. The isolated square planar AuO4 units are stacked along the a-axis and are linked by LnO6- and LnO6+1-polyhedra. One of the oxygen atoms is exclusively coordinated by trivalent lanthanides, in tetrahedral geometry. The lanthanoid aurates decompose between 700 and 900°C into Ln2O3, Au and O2. The magnetic moments μeff(Gd3AuO6) = 7.9 μB and, at 20°C respectively, μeff(Sm3AuO6) = 1.55 μB as well as μeff(Eu3AuO6) = 3.5 μB confirm that the lanthanides are trivalent. The UV/VIS absorption spectra can be interpreted at assuming free ions. Wiley-VCH Verlag GmbH, 2001.
