146232-42-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 146232-42-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,2,3 and 2 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 146232-42:
(8*1)+(7*4)+(6*6)+(5*2)+(4*3)+(3*2)+(2*4)+(1*2)=110
110 % 10 = 0
So 146232-42-0 is a valid CAS Registry Number.

Synthesis and Properties of 1,8-Di(2-thienyl)-, 1,8-Bs(5,2'-bithiophene-2-yl)-, 1,8-Bis(5,2':5',2''-terthiophene-2-yl)-, and 1,8-Bis(5,2':5',2'':5'',2'''-quaterthiophene-2-yl)naphthalenes and Related Compounds

, p. 3735 - 3748 (1993)

1,8-Di(2-thienyl)-, 1,8-bis(5,2'-bithiophene-2-yl), 1,8-bis(5,2':5',2''-terthiophene-2-yl)-, and 1,8-bis(5,2':5',2'':5'',2'''-quaterthiophene-2-yl)naphthalenes (1a, 1b, 1c, and 1d, respectively) were synthesized starting from 1,8-dibromonaphthalene by application of NiCl2(dppp)-catalyzed coupling of aryl bromides with thienylmagnesium bromides.For comparison with these compounds, 1-(2-thienyl)-, 1-(5,2'-bithiophene-2-yl)-, 1-(5,2':5',2''-terthiophene-2-yl)-, and 1-(5,2':5',2'':5'',2'''-quaterthiophene-2-yl)naphthalenes (2a-d) were also prepared.Inspection of 1H and 13C NMR and UV/Vis data of 1a-d and 2a-d including X-ray single crystal structure data of 1b suggests that the planes of two oligothiophene units of 1a-d are approximately parallel to each other and are at large angles to the naphthalene ring.In accordance with these findings, CV oxidation potential data show that the radical cations formed from 1a-d are stabilized by intramolecular electron transfer interaction of the two oligothiophene units.

Synthesis and properties of naphthalenes carrying two cofacially oriented α-oligothiophene units at the peri positions

Kuroda,Nakayama,Hoshino,Furusho

, p. 7553 - 7556 (1992)

Two cofacially oriented (oligo)thiophene units of 1,8-di(2-thienyl)-, 1,8-bis(5,2'-bithiophene-2-yl)-, and 1,8-bis(5,2':5',2''-terthiophene-2-yl)naphthalenes, which were synthesized starting from 1,8-dibromonaphthalene, interact with each other to stabilize the radical cations of these compounds, thus decreasing their CV oxidation potentials.
