Check Digit Verification of cas no

The CAS Registry Mumber 20859-10-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,5 and 9 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20859-10:
(7*2)+(6*0)+(5*8)+(4*5)+(3*9)+(2*1)+(1*0)=103
103 % 10 = 3
So 20859-10-3 is a valid CAS Registry Number.

In situ generation of 2,3-allenolates in the coupling of secondary homopropargylic alcohols and aldehydes

Miranda, Pedro O.,Ramírez, Miguel A.,Padrón, Juan I.,Martín, Víctor S.

, p. 283 - 286 (2006)

A study on a novel oxonia [3,3]-sigmatropic rearrangement as competitive alternative pathway to the acetylenic Prins cyclization on the addition of secondary homopropargylic alcohols to aldehydes catalyzed by iron(III) is described. 'Ab initio' theoretica

The cinchona primary amine-catalyzed asymmetric epoxidation and hydroperoxidation of α,β-unsaturated carbonyl compounds with hydrogen peroxide

Lifchits, Olga,Mahlau, Manuel,Reisinger, Corinna M.,Lee, Anna,Fares, Christophe,Polyak, Iakov,Gopakumar, Gopinadhanpillai,Thiel, Walter,List, Benjamin

supporting information, p. 6677 - 6693 (2013/06/05)

Using cinchona alkaloid-derived primary amines as catalysts and aqueous hydrogen peroxide as the oxidant, we have developed highly enantioselective Weitz-Scheffer-type epoxidation and hydroperoxidation reactions of α,β-unsaturated carbonyl compounds (up to 99.5:0.5 er). In this article, we present our full studies on this family of reactions, employing acyclic enones, 5-15-membered cyclic enones, and α-branched enals as substrates. In addition to an expanded scope, synthetic applications of the products are presented. We also report detailed mechanistic investigations of the catalytic intermediates, structure-activity relationships of the cinchona amine catalyst, and rationalization of the absolute stereoselectivity by NMR spectroscopic studies and DFT calculations.

Stereocontrolled total synthesis of (+)-leucascandrolide A

Paterson, Ian,Tudge, Matthew

, p. 343 - 347 (2007/10/03)

Apparently no longer available from its natural source is the potent cytotoxic and antifungal agent leucascandrolide A (1), which was initially isolated from a New Caledonian calcareous sponge. A highly stereocontrolled total synthesis of this structurally unique macrolide commences with a Jacobsen asymmetric hetero Diels-Alder reaction to configure the tetrahydropyran ring. An efficient endgame relies on two Mitsunobu reactions, the first to generate the 18-membered macrolactone and the second to attach the oxazole-bearing side chain.
