Check Digit Verification of cas no

The CAS Registry Mumber 1189758-59-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,7,5 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1189758-59:
(9*1)+(8*1)+(7*8)+(6*9)+(5*7)+(4*5)+(3*8)+(2*5)+(1*9)=225
225 % 10 = 5
So 1189758-59-5 is a valid CAS Registry Number.

Electrochemically induced intermolecular anion transfer

Curiel, David,Beer, Paul D.,Tarraga, Alberto,Molina, Pedro

, p. 7534 - 7538 (2009)

Two macrocyclic anion receptors with the proper signaling units were designed to control intermolecular anion transfer using an electrochemical stimulus. The solubility of both receptors drastically improved when one equivalent of benzoate was added to the suspension in the NMR tube. Macrocycles 1 and 2 were prepared via multistep synthetic pathways. An important enhancement of the MLCT emission intensity was initially seen when benzoate was added to a solution of macrocycles 1. Spectroelectrochemical experiments were conducted for a mixture which contained receptors 1,2 and benzoate in equimolar concentration in acetone. The reversibility of the anion transfer could be shown and hence, electrochemical reduction of ferrocenium to ferrocene at -0.2 V was simultaneously accompanied by an enhancement of the emission intensity.
