Check Digit Verification of cas no

The CAS Registry Mumber 545411-28-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,5,4,1 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 545411-28:
(8*5)+(7*4)+(6*5)+(5*4)+(4*1)+(3*1)+(2*2)+(1*8)=137
137 % 10 = 7
So 545411-28-7 is a valid CAS Registry Number.

Investigations on 1-metallaindanes

Goedheijt, Marcel Schreuder,Nijbacker, Tom,Horton, Andrew D.,De Kanter, Franciscus J. J.,Akkerman, Otto S.,Bickelhaupt, Friedrich

, p. 638 - 643 (2007/10/03)

1-Mercuraindane (6) was prepared in three steps from 1-bromo-2-(2-bromoethyl) benzene (3) and converted into 1-magnesaindane (1) by reaction with magnesium. In solution, 6 was observed to occur in a remarkable dimer/trimer equilibrium, whereas 1 forms a dimer. From 1 and dichlorozirconocene, the 1-zirconaindane 2 was obtained, which reacted with B(C6F5)3 to form the adduct 13. According to spectroscopic data, 13 is formed by attack of the p-methylene carbon atom at the boron atom and has a zwitterionic structure with weak interactions between the zirconium ion and one of the ortho-fluorine atoms.
