Check Digit Verification of cas no

The CAS Registry Mumber 104690-02-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,6,9 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 104690-02:
(8*1)+(7*0)+(6*4)+(5*6)+(4*9)+(3*0)+(2*0)+(1*2)=100
100 % 10 = 0
So 104690-02-0 is a valid CAS Registry Number.

Synthesis, Reactivity and Structural Aspects of Some Organotellurium(IV) Oxinates

Srivastava, T. N.,Singh, Jai Deo,Mehrotra, Shashi

, p. 849 - 851 (2007/10/02)

Organotellurium oxinates of the type R2TeL2 have been prepared in quantitative yields by the interaction of R2TeX2 with NaL or HL.R2TeL2 react with haloacetic acids (R'COOH) to yield mixed ligand complexes of the type R2Te(OCOR')L.The proton magnetic and IR spectra suggest that R2TeL2 possess two types of oxine groups one of which is bidentate and the other unidentate.The tellurium atom thus prefers to remain pentacoordinate in an octahedral geometry, one of the sites being occupied by a lone pair.
