Check Digit Verification of cas no

The CAS Registry Mumber 77624-54-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,2 and 4 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77624-54:
(7*7)+(6*7)+(5*6)+(4*2)+(3*4)+(2*5)+(1*4)=155
155 % 10 = 5
So 77624-54-5 is a valid CAS Registry Number.

A (125)Te Moessbauer study of hexahalotellurates, pentahalotellurates, and tetrahaloaryltellurates

Dance, Nigel S.,Dobud, Pablo,Jones, Colin H. W.

, p. 913 - 917 (2007/10/02)

The (125)Te Moessbauer spectra of a number of hexahalotellurates have been measured and no significant effects of the size or symmetry of the cation on the Moessbauer parameters were observed.The mixed hexahalotellurates, M2TeX4Y2 (X,Y = Cl, Br, or I), do not exhibit a quadrupole splitting, Δ, and the trends in δ with variation in X and Y are discussed.The pentahalotellurates MTeCl5, MTeBr5, and MTeBr4Cl also yield single line spectra and this is interpreted as evidence of intermolecular bridging.The tetrahaloaryl tellurates MArTeX4 and MArTeX3Y (X,Y = Cl, Br, or I) have been studied and the trends in Δ with variation X and Y are consistent with an additive model.The trends in δ are more complex.
