Check Digit Verification of cas no

The CAS Registry Mumber 13826-63-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,8,2 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 13826-63:
(7*1)+(6*3)+(5*8)+(4*2)+(3*6)+(2*6)+(1*3)=106
106 % 10 = 6
So 13826-63-6 is a valid CAS Registry Number.

Anharmonicity-induced glasslike transition in a plastic crystal without α relaxation

Johari,Collins,Feyerherm

, p. 5827 - 5830 (2000)

In the low-temperature crystal phase of TlNO2 studied by dielectric spectroscopy (10 mHz to 3 GHz), the α-relaxation process does not evolve, and the molecular dynamics is controlled only by one relaxation process with Arrhenius energy of 19.8 kJ mol-1. Its characteristic time is comparable to the measurement time scale at ~62 K, where its Cp, the expansivity α, and the T derivative of the mean-square atomic displacement decrease in a manner similar to that on the dynamic freezing of the α process. However, neutron powder diffraction measurements show no evidence for two-site occupancy or orientational disordering [Phys. Rev. B 57, 11 125 (1998)]. We propose a nonconfigurational mechanism for this dynamics, namely, that when a vacancy appears at a Tl site, the anharmonicity of librations of the NO2- ion increases, which changes the mean dipole vector and raises Cp and α. When the vacancy diffusion does not occur during the measurement period, the anharmonic contribution vanishes and Cp and α decrease. 2000 The American Physical Society.

Neutron diffraction study of orientational freezing in TlNO2 and CsNO2

Feyerherm,Collins,Johari

, p. 11125 - 11131 (1998)

The low-temperature crystal structure and temperature dependence of lattice parameters and atomic meansquare displacements of thallium nitrite (TlNO2) and cesium nitrite (CsNO2) have been determined by neutron powder diffraction. Previously, based on specific heat and dielectric relaxation measurements, both compounds were reported to exhibit partial dynamic orientational disorder of the NO2 anions below the transition temperatures 282.4 and 209.2 K, respectively, from the plastic, disordered high-temperature phase I to the low-temperature phase II. A glass-transition-like freezing of the associated reorientational motions was reported to occur below 60 and 40 K, respectively. In the present study, we could not confirm the previous space-group assignments Cmmm and R3m for the low-temperature crystal structure of TlNO2 and CsNO2, respectively. Instead, we find that these compounds have space group P3121 in phase II. A structural model assuming that all atoms occupy unique sites and the two oxygen atoms of each NO2 anion are located on crystallographically equivalent sites gives excellent agreement with the observed data. This model leaves no large-angle orientational degrees of freedom for the NO2 anion anticipated by previous studies. The glasslike behavior apparent in specific heat and dielectric relaxation studies can only be reconciled with our results if the glasslike transition involves relatively small displacements or reorientations of the NO2 anion. This would be a novel type of glasslike transition.
