Check Digit Verification of cas no

The CAS Registry Mumber 70714-63-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,7,1 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 70714-63:
(7*7)+(6*0)+(5*7)+(4*1)+(3*4)+(2*6)+(1*3)=115
115 % 10 = 5
So 70714-63-5 is a valid CAS Registry Number.

BAND EDGE EXCITION SPECTRA IN Sm MONOCHALCOGENIDES.

Kurita,Kaneko,Koda

, p. 463 - 466 (2008/10/08)

Reflection spectra have been measured on semiconducting SmS, SmSe and SmTe single crystals at 2 K in the photon energy region from 3 to 6 ev. From a comparison of the spectra in these Sm monochalcogenides with those in BaS and BaSe, the reflection peaks observed in this photon energy region are identified as the Wannier excitons associated with the band-edges at the X-point and the GAMMA -point. Temperature dependence of the reflection peaks and the electroreflectance spectra of SmSe support this identification. The energy band structure of semiconducting Sm monochalcogenides is discussed on the basis of the observed exciton spectra.
