Purification Methods

It is now available commercially. After the sequential removal of C60 and C7 0 fullerenes from soot extracts (see above) on gel permeation columns (e.g. Buckyclutcher 1 column), C7 6 and higher fullerenes are obtained . These are further separated on a Trident-TriDNP functionalised silica column. After two HPLC runs on a C1 8 reverse phase (Vydac 201 TP C1 8) column and eluting with 1:1 MeCN/toluene, pure C7 6 fullerene is obtained. The identity is confirmed by HPLC/GPC system with Waters 600E UV/VIS detection, mass and NMR spectroscopy. [Seleque et al.

Inc, Pennington, NJ, 1994 ISBN 1566770823, Diederich & Whetten Acc Chem Res 25 119 1992, Diederich et al. Science 254 1768 1991.]

Check Digit Verification of cas no

The CAS Registry Mumber 135113-15-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,1,1 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 135113-15:
(8*1)+(7*3)+(6*5)+(5*1)+(4*1)+(3*3)+(2*1)+(1*5)=84
84 % 10 = 4
So 135113-15-4 is a valid CAS Registry Number.
