Check Digit Verification of cas no

The CAS Registry Mumber 1268257-83-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,2,5 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1268257-83:
(9*1)+(8*2)+(7*6)+(6*8)+(5*2)+(4*5)+(3*7)+(2*8)+(1*3)=185
185 % 10 = 5
So 1268257-83-5 is a valid CAS Registry Number.

Synthesis, characterization, and electrochemical study of diiron organometallic derivatives of 2,6-dibutyl-4,8-dimethyl-1,5-dihydro-S-indacene

Amshumali,Arancibia, Veronica,Manriquez, Juan M.,Chavez, Ivonne

, p. 727 - 731 (2013/08/23)

A new fused ring compound, 2,6-dibutyl-4,8-dimethyl-1,5-dihydro-s-indacene (VII) (H2L), has been synthesized from 2,5-dimethyl-1,4- dibromomethylbenzene in almost quantitative yield. Two organomtallic binuclear complexes, [CpFe-L-FeCp] (1) and the mixed-valence compound [CpFe-L-FeCp] + BF-4 (2), have been characterized by spectroscopic and electrochemical techniques. The cyclic voltammogram of 1 exhibits a potential difference of 668 mV between two redox peaks and the UV-vis-NIR spectra of compound 2 shows an intervalance charge transfer band at 1794 nm. The information gathered by these techniques indicates that the studied binuclear complex has strong interaction between the two metal centres.
