6544-76-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6544-76-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,4 and 4 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6544-76:
(6*6)+(5*5)+(4*4)+(3*4)+(2*7)+(1*6)=109
109 % 10 = 9
So 6544-76-9 is a valid CAS Registry Number.

Electrocyclization of cis-dienals in organic synthesis: A new and versatile synthetic method for the preparation of aryl- and heteroaryl-fused coumarins

Hon, Yung-Son,Tseng, Tze-Wei,Cheng, Chia-Yi

supporting information; experimental part, p. 5618 - 5620 (2010/01/31)

Benzo-, furo-, thieno-, and pyrido[f]coumarins were prepared by generating the 2H-pyran-2-one moieties from the oxidation of the corresponding 2H-pyran rings, which were formed in situ from the electrocyclization of cis-dienals.

Efficient and convenient synthesis of angular furanocoumarins from hydroxycoumarins

Harayama, Takashi,Nishita, Yoshitaka

, p. 1986 - 1988 (2007/10/03)

Angular furanocoumarins (1) were synthesized via sequential reactions of vinylation of halo-hydroxycoumarins (5 or 6) with chlorodimethylvinylsilane (8) and Pd catalyst, oxidation of Tl(NO3)3 in methanol, and treatment with acid.

13C-NMR Spectra and Carbon-Proton Coupling Constants of Variously Annulated Furocoumarins

Guiotto, A.,Manzini, P.,Chilin, A.,Pastorini, G.,Rodighiero, P.

, p. 649 - 656 (2007/10/02)

The 13C-nmr spectra of variously annulated methylfurocoumarins are reported.The assignemnts of chemical shifts for all the C resonances has been achieved by using carbon-proton coupling constants, relaxation efficiency considerations and shift effects caused by the introduction of methyl groups at various positions of the furocoumarin nucleus.Substituent effects on 13C chemical shifts and carbon-proton coupling constants are discussed.
