120085-98-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 120085-98-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,0,8 and 5 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 120085-98:
(8*1)+(7*2)+(6*0)+(5*0)+(4*8)+(3*5)+(2*9)+(1*8)=95
95 % 10 = 5
So 120085-98-5 is a valid CAS Registry Number.

Synthesis of new copper(I)-complexed rotaxanes via click chemistry

Durot, Stéphanie,Mobian, Pierre,Collin, Jean-Paul,Sauvage, Jean-Pierre

, p. 8496 - 8503 (2008/12/21)

The Cu(I)-catalyzed dipolar cycloaddition of azides and terminal alkynes ('click' chemistry) has been used as a mild and efficient stoppering reaction for the preparation of new copper(I)-complexed rotaxanes.

Synthesis of bis-porphyrins containing a 2,9-diphenyl-1,10-phenanthroline spacer

Chabdon-Noblat, Sylvie,Sauvage, Jean-Pierre

, p. 5123 - 5132 (2007/10/02)

The synthesis of bis-porphyrins disposed in an oblique fashion is described. The tetrapyrrole rings are linked via a 2,9-diphenyl-1,10-phenanthroline spacer. Two routes have been investigated: a step wise procedure and a direct strategy involving a double cyclisation step. From the bis-free base porphyrin, synthesized with an overall yield of 1% from 2,9-di(p-tolyl)-1,10-phenanthroline, an unsymmetrical zinc (II) porphyrin free base system was prepared and isolated in view of excited state energy and electron transfer.
