Check Digit Verification of cas no
The CAS Registry Mumber 2092-17-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,9 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2092-17:
(6*2)+(5*0)+(4*9)+(3*2)+(2*1)+(1*7)=63
63 % 10 = 3
So 2092-17-3 is a valid CAS Registry Number.

Vibrational spectra and structure of cadmium(II) thiocyanate
Goel, R. G.
, p. 557 - 558 (1981)
Infrared and Raman spectral data (4000-50 cm-1) of cadmium(II) thiocyanate are consistent with a polymeric structure having a centro-symmetric octahedral coordination polyhedron around cadmium.
Photoluminescence of Ba(SCN)2:Eu2+
Wickleder, Claudia
, p. 10 - 13 (2008/10/09)
The luminescence properties of Eu2+ in the novel host lattice Ba(SCN)2 has been investigated. At low temperature a strong green emission is observed with a maximum at 511nm, which is strongly quenched with increasing temperatures. The excitation spectrum yielded a Stokes shift which clearly shows the presence of a 5d → 4f emission. The quenching behaviour can be explained by the fact that the lowest 5d state is located at slightly lower energy than the conduction band of the host lattice. At increasing temperature thermal occupation of the conduction band occurs followed by nonradiatively excitonic relaxation to the ground state. The luminescence properties of Ba(SCN)2:Eu2+ are very similar to those of Sr(SCN)2:Eu2+.
