91281-15-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91281-15-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,2,8 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91281-15:
(7*9)+(6*1)+(5*2)+(4*8)+(3*1)+(2*1)+(1*5)=121
121 % 10 = 1
So 91281-15-1 is a valid CAS Registry Number.

Two dibenzothiophene (DBT)-based phosphine oxide hosts, named 4-diphenylphosphoryl dibenzothiophene (DBTSPO) and 4,6-bis(diphenylphosphoryl) dibenzothiophene (DBTDPO), were prepared by short-axis substitution with the aim to selectively adjust electrical

Bidentate Phosphines of Heteroarenes: 4,6-Bis(diphenylphosphino)dibenzofuran and 4,6-Bis(diphenylphosphino)dibenzothiophene

Haenel, Matthias W.,Jakubik, Dieter,Rothenberger, Eveline,Schroth, Gerhard

, p. 1705 - 1710 (2007/10/02)

Twofold lithiathion of dibenzofuran (6) and dibenzothiophene (12) with n-butyllithium/ N,N,N',N'-tetramethylethylenediamine (TMEDA) in n-hexane or n-heptane followed by the reaction with chlorodiphenylphosphine yielded the title compounds 4 and 5, respectively.The monophosphines 4-(diphenylphosphino)dibenzofuran (11) and 4-(diphenylphosphino)dibenzothiophene (15) were obtained analogously via the monolithium compounds 9 and 14 of the heteroarenes.In the case of dibenzofuran (6), it was shown that mono- and dilithiation is controlled by temperature.Key Words: Phoshine ligands/ Dibenzofuran/ Dibenzothiophene/ Lithium compounds/ Multiple lithiation
