Check Digit Verification of cas no

The CAS Registry Mumber 163082-04-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,0,8 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 163082-04:
(8*1)+(7*6)+(6*3)+(5*0)+(4*8)+(3*2)+(2*0)+(1*4)=110
110 % 10 = 0
So 163082-04-0 is a valid CAS Registry Number.

Several generations of chemoenzymatic synthesis of oseltamivir (Tamiflu): Evolution of strategy, quest for a process-quality synthesis, and evaluation of efficiency metrics

Werner, Lukas,Machara, Ales,Sullivan, Bradford,Carrera, Ignacio,Moser, Michael,Adams, David R.,Hudlicky, Tomas,Andraos, John

, p. 10050 - 10067 (2012/01/15)

Four generations of chemoenzymatic approaches to oseltamivir are presented. The first two generations relied on the use of cyclohexadiene-cis-diol derived enzymatically from bromobenzene. The third and fourth generation used the corresponding diol obtaine

Total synthesis and biological evaluation of Amaryllidaceae alkaloids: narciclasine, ent-7-deoxypancratistatin, regioisomer of 7-deoxypancratistatin, 10b-epi-deoxypancratistatin, and truncated derivatives.

, p. 8726 - 8743 (2007/10/03)

Biocatalytic approaches have yielded efficient total syntheses of the major Amaryllidaceae alkaloids, all based on the key enzymatic dioxygenation of suitable aromatic precursors. This paper discusses the logic of general synthetic design for lycoricidine, narciclasine, pancratistatin, and 7-deoxypancratistatin. Experimental details are provided for the recently accomplished syntheses of narciclasine, ent-7-deoxypancratistatin, and 10b-epi-deoxypancratistatin via a new and selective opening of a cyclic sulfate over aziridines followed by aza-Payne rearrangement. The structural core of 7-deoxypancratistatin has also been degraded to a series of intermediates in which the amino inositol unit is cleaved and deoxygenated in a homologous fashion. These truncated derivatives and the compounds from the synthesis of the unnatural derivatives have been tested against six important human cancer cell lines in an effort to further develop the understanding of the mode of action for the most active congener in this group, pancratistatin. The results of the biological activity testing as well as experimental, spectral, and analytical data are provided in this manuscript for all relevant compounds.

Structure assignment of aminoconduritols by 15N NMR correlation spectroscopy; synthesis of a positional isomer of 7-deoxypancratistatin

Schilling, Stefan,Rinner, Uwe,Chan, Collin,Ghiviriga, Ion,Hudlicky, Tomas

, p. 1659 - 1667 (2007/10/03)

A positional isomer of 7-deoxypancratistatin was synthesized in 12 steps from epoxyaziridines 4 and 5. An intermolecular opening of the aziridine rather than the epoxide in the early stages of the synthesis led to 13, which did not match the properties of
