Check Digit Verification of cas no

The CAS Registry Mumber 188902-69-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,9,0 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 188902-69:
(8*1)+(7*8)+(6*8)+(5*9)+(4*0)+(3*2)+(2*6)+(1*9)=184
184 % 10 = 4
So 188902-69-4 is a valid CAS Registry Number.

Synthesis and metal complexation of two vic-dioxime derivatives of calix[4]arenes

Deligoez, Hasalettin,Yilmaz, Mustafa

, p. 391 - 400 (1997)

Two new vic-dioxime compounds of calix[4]arene and their transition metal complexes were synthesized from 28-[(4-aminobenzyl)oxy]-25,26,27-tribenzoyloxycalix[4]arene and amphi-chloroglyoxime or amphi-dichloroglyoxime. The complexes of these compounds with Ni(II), Cu(II) and Co(II) ions were investigated. All of the complexes of these ligands are tetrahedral with a metal-ligand ratio of 1:2. The prepared compounds were characterised based on 1H NMR and IR spectra as well as elemental analyses.
