111458-32-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 111458-32-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,4,5 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 111458-32:
(8*1)+(7*1)+(6*1)+(5*4)+(4*5)+(3*8)+(2*3)+(1*2)=93
93 % 10 = 3
So 111458-32-3 is a valid CAS Registry Number.

The Synthesis of Bridged Oligophenylenes from Fluorene 1. Terphenyls and Quaterphenyls

Kelley, Charles J.,Ghiorghis, Alem,Kauffman, Joel M.

, p. 2701 - 2733 (2007/10/03)

Improved methods are presented for the alkylation of fluorene (2) to 9,9- dialkylfluorenes (3-6) free from 9-monoalkylfluorenes.Mono- and dihalogenated derivatives of 2-6 are reported as are a variety of ring substituted 9,9-dialkylfluorenes.Halogenated 9,9-dialkylfluorenes and aryl or methyl Grignard reagents were cross-coupled in Pd-catalyzed reactions to generate a series of novel p-oligophenylenes (four terphenyls (26, 27, 29 and 31c) and nineteen quterphenyls (33-6, 64-71 and 73-79)) each possessing one or two dialkylated methylene bridges between aromatic rings.Each bridged oligophneylene showed enhanced solubility, high quantum efficiency and photochemical stability.A number of quaterphenyls incorporated substituents which extended the conjugation of the oligophenylene chromophore.
