124477-12-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 124477-12-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,4,7 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 124477-12:
(8*1)+(7*2)+(6*4)+(5*4)+(4*7)+(3*7)+(2*1)+(1*2)=119
119 % 10 = 9
So 124477-12-9 is a valid CAS Registry Number.

Attempts to improve the overall stereoselectivity of the Ireland-Claisen rearrangement

Chen, Chi-Li,Namba, Kosuke,Kishi, Yoshito

body text, p. 409 - 412 (2009/07/18)

(Chemical Equation Presented) With focus on the steric effects present in the transition states for the [3,3]-sigmatropic rearrangement, the substrate 5 has been designed to improve the overall stereoselectivity of the Ireland-Claisen rearrangement. Exper

Radical Cyclization Routes to Bridged Pyranosides as Precursors of Densely Functionalized Cycloalkanes

Alonso, R. A.,Vite, G. D.,McDevitt, R. E.,Fraser-Reid, B.

, p. 573 - 584 (2007/10/02)

Glycals derived from hexapyranoses permit the incorporation of iodine at C-2 as well as elaboration of an olefinic residue via the C-5-hydroxymethyl group.Radical cyclization of these functionalities leads to bicyclic systems whose bridge sizes depend on

CONVENIENT SYNTHESES OF SUBSTITUTED PYRANOID GLYCALS FROM THIOPHENYL GLYCOSIDES AND GLYCOSYL PHENYLSULFONES

Fernandez-Mayoralas, Alfonso,Marra, Alberto,Trumtel, Michel,Veyrieres, Alain,Sinay, Pierre

, p. 2537 - 2540 (2007/10/02)

A series of substituted thiophenyl glycosides and glycosyl phenylsulfones were converted in high yield into glycals after reductive lithiation with lithium naphthalenide, followed by elimination of the substituent at C-2.
