Check Digit Verification of cas no

The CAS Registry Mumber 61948-94-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,9,4 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 61948-94:
(7*6)+(6*1)+(5*9)+(4*4)+(3*8)+(2*9)+(1*4)=155
155 % 10 = 5
So 61948-94-5 is a valid CAS Registry Number.

Diaryltellurium(IV) carboxylates: Synthesis via telluroxides and their characterization

Verma,Soni, Daya,Verma, Sunil

, p. 231 - 241 (2000)

The synthesis of some new diaryltellurium(IV) dicarboxylates (salicylate, benzoate, cinnamate) and carboxylales (oxalate, o-phthalate, succinate) by the reactions of bis(p-methoxyphenyl)telluroxide and bis(p-hydroxyphenyl)telluroxide with the corresponding carboxylic acid is reported. The resulting carboxylates have been subjected to elemental analyses, conductance and cryoscopic measurements, infra-red and proton magnetic resonance spectral studies. Solution studies reflect the non-ionic nature of these compounds. Infra-red spectral studies predict the unidentate nature of salicylate, benzoate and cinnamate and bidentate nature of oxalate, o-phthalate and succinate groups. A PMR spectral study confirms their proposed stoichiometry. These compounds possess a trigonal bipyramidal structure with a tetra-coordinate central tellurium atom.
