Check Digit Verification of cas no
The CAS Registry Mumber 12008-06-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,0 and 8 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 12008-06:
(7*1)+(6*2)+(5*0)+(4*0)+(3*8)+(2*0)+(1*6)=49
49 % 10 = 9
So 12008-06-9 is a valid CAS Registry Number.

Magnetic field dependence of the rare earth B12 icosahedral cluster compound GdB18Si5
Mori, Takao
, p. 2803 - 2807 (2005)
Magnetic field dependence of the rare earth B12 icosahedral cluster compound GdB18Si5 was investigated. GdB 18Si5 is the only system in the rare earth boron icosahedral cluster compounds in which 3 dimensional long range order has been observed. GdB18Si5 exhibits an antiferromagnetic transition at TN = 3.2 K, with the spins antiferromagnetically aligned in-plane, perpendicular to [0 0 1]. The magnetic phase diagram was determined for the field applied along the c-axis. The general magnitude of field corresponds to the temperature scale. An interesting dependence at low magnetic fields was observed when the field was varied in-plane, with a reorientation of the spin, a spin flip, appearing to occur at fields below 300 G.

Submicron crystalline rare-earth hexaborides (RB6; R = Sm, Eu, Gd, and Tb) have been successfully prepared by a facile one-step solid-state reaction of RCl3·OH2O, B2O3, and Mg powder in an autoclave at the relatively low temperature of 500°C. By controlling the reaction, conditions, submicronsized cubes (RB6) and rod- and needlelike SmB6 are obtained. The possible growth mechanism of the 1D SmB6 structures has also been discussed. The XRD patterns of the products show that all of the hexaborides can be indexed to a cubic phase with high crystallinity and high purity. The field-emission scanning electron microscopy (FESEM) and TEM images display their cube-, rod-, and needlelike morphologies. The selected-area electron diffraction (SAED) patterns reveal the single-crystalline nature of the products.
Thermodynamic functions for heavy rare-earth hexaborides as measured by calorimetry in the temperature range from 5 to 300 K
Sirota,Novikov,Vinokurov
, p. 1722 - 1725 (2007/10/03)
The molar heat capacities of gadolinium, terbium, and dysprosium hexaborides were measured over the temperature range 5-300 K. The temperature dependences and the standard values of the enthalpy, entropy, and the Gibbs energy were calculated by taking into account the nuclear contribution to the heat capacity.
