Check Digit Verification of cas no

The CAS Registry Mumber 343313-84-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,3,3,1 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 343313-84:
(8*3)+(7*4)+(6*3)+(5*3)+(4*1)+(3*3)+(2*8)+(1*4)=118
118 % 10 = 8
So 343313-84-8 is a valid CAS Registry Number.

Supramolecular chemistry: Molecular recognition and self-assembly using rigid spacer-chelators bearing cofacial terpyridyl palladium(II) complexes separated by 7 A

Sommer,Rheingold,Goshe,Bosnich

, p. 3940 - 3952 (2007/10/03)

Partially and fully aromatic molecular spacers bearing two symmetrically bound terpyridyl chelators have been prepared. These spacer-chelators were constructed to dispose the two terpyridyl ligands and their complexes with square planar metals cofacially with a separation of about 7 A between the two metals. Dipalladium(II) complexes of these spacer-chelators were prepared and characterized. These palladium complexes readily form large molecular rectangles with a linear linker such as 4,4′-dipyridyl. The dichlorodipalladium complex of the partially reduced spacer-chelator is capable of incarcerating planar aromatic and coordination compounds as guests. A crystal structure showing the incorporation of 9-methylanthracene has been determined. A 9-methylanthracene lies completely within the 7 A space provided by the cleft formed by the two cofacially disposed chloro-palladium-terpyridyl units. The crystal structure shows additional π-stacking interactions between a second 9-methylanthracene and neighboring receptors.
