81581-29-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81581-29-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,5,8 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81581-29:
(7*8)+(6*1)+(5*5)+(4*8)+(3*1)+(2*2)+(1*9)=135
135 % 10 = 5
So 81581-29-5 is a valid CAS Registry Number.

Simple synthesis of eudesmin through oxidative coupling of carbanions and reductive catalytic hydrogenation of diketo diester

Jung, Jae-Chul,Park, Oee-Sook

, p. 1665 - 1673 (2008/02/01)

A simple synthesis of eudesmin (1) is described. The key fragments were diol 13, dicarbethoxyethane 4, and diketo diester 5, which were prepared via reductive catalytic hydrogenation and oxidative intermolecular coupling of carbanions. This method is useful to generate the core skeleton of an endo-endo furofuran ring. Copyright Taylor & Francis Group, LLC.

Synthesis and N.m.r. Spectra of 2,6- and 2,4-Diaryl-3,7-dioxabicyclooctanes

Pelter, Andrew,Ward, Robert S.,Watson, Derrick J.,Jack, Ibiba R.

, p. 183 - 190 (2007/10/02)

A series of isomeric 2,6- and 2,4-diaryl-3,7-dioxabicyclooctanes have been prepared via the corresponding threo, and erythro-dioxo-diesters.Comparison of their 1H and 13C n.m.r. spectra reveals small differences in chemical shifts and coupling constants which could be diagnostic in assigning structures to such compounds.The structure of 4-hydroxysesamin has been confirmed by direct correlation with sesamin.
