721923-83-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 721923-83-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,1,9,2 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 721923-83:
(8*7)+(7*2)+(6*1)+(5*9)+(4*2)+(3*3)+(2*8)+(1*3)=157
157 % 10 = 7
So 721923-83-7 is a valid CAS Registry Number.

Recognition of the chain length of α,ω-diamines by a meso-ternaphthalene derivative with two crown ethers

Tsubaki,Tanaka,Furuta,Kinoshita,Fuji

, p. 6089 - 6093 (2000)

A new ditopic receptor 2 consisting of a meso-ternaphthalene backbone and two crown rings has been shown to selectively complex and transfer dipicrate of 1,9-diaminononane and 1,10-diaminodecane from aqueous solution into the organic phase. (C) 2000 Elsevier Science Ltd.

Configurationally defined sexi- and octinaphthalene derivatives: Synthesis and optical properties

Furuta, Takumi,Tanaka, Kiyoshi,Tsubaki, Kazunori,Fuji, Kaoru

, p. 4431 - 4441 (2007/10/03)

The copper mediated oxidative coupling of optically active quaternaphthalenes having a 2-hydroxynaphthyl moiety gave configurationally defined optically active octinaphthalenes. The absolute configuration was determined by comparison with products of [6+2] coupling. The CD spectra of bi-, ter-, quater-, sexi- and octinaphthalenes suggested that the absolute configuration of the chiral axis could be deduced from the intensity of their Cotton effects.

Use of meso-ternaphthalene derivatives: Linear recognition of the α,ω-diamines by homoditopic receptors

Tsubaki, Kazunori,Tanaka, Hiroyuki,Furuta, Takumi,Tanaka, Kiyoshi,Kinoshita, Takayoshi,Fuji, Kaoru

, p. 5611 - 5617 (2007/10/03)

The new ditopic receptors 1-3 consisting of a meso-ternaphthalene backbone and two crown ether rings have been synthesized. Hosts 2 and 3 have been shown to selectively complex and transfer the dipicrates, 1,9-diaminononane and 1,10-diaminodecane, from aqueous solution into the organic phase.

Synthesis of configurationally defined sexi-and octinaphthalene derivatives

Fuji, Kaoru,Furuta, Takumi,Tanaka, Kiyoshi

, p. 169 - 171 (2007/10/03)

equation presented Configurationally defined optically active octinaphthalenes were synthesized using the oxidative coupling of optically active quaternaphthalenes with a 2-hydroxynaphthol moiety as a key reaction. The absolute configuration was determined by comparison with products of [6 + 2] coupling.
