Check Digit Verification of cas no

The CAS Registry Mumber 83665-28-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,6,6 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 83665-28:
(7*8)+(6*3)+(5*6)+(4*6)+(3*5)+(2*2)+(1*8)=155
155 % 10 = 5
So 83665-28-5 is a valid CAS Registry Number.

Synthesis, Structures and Properties of CF3S-Substituted Tellurium Compounds

Boese, Roland,Dworak, Juergen,Haas, Alois,Pryka, Michael

, p. 477 - 480 (2007/10/02)

New preparations for the following compounds are described: Te(SCF3)2, Te(NSO)2, and Cl2Te(NSO)2.The catalytic or thermal SO2 elimination from Cl2Te(NSO)2 affords a coordinated or non-coordinated thiachalcogenadiazole.Conversions of these compounds are reported.Evidence for the proposed mechanism for the reaction between Te(NSO)2 and SbCl5 is provided.Cl4Te2N2(SCF3)2, prepared from TeCl4 and CF3SN(SiMe3)2, reacts with LiN(SiMe3)2 to form 4Te2N2(SCF3)2.An X-ray structural analysis of Cl4Te2N2(SCF3)2 is presented. - Key Words: Tellurium, bis(sulfinylamido)-, bis(trifluoromethylthio)- / Thiachalcogenadiazole / Ditelluradiazetidine
