16424-32-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 16424-32-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,4,2 and 4 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 16424-32:
(7*1)+(6*6)+(5*4)+(4*2)+(3*4)+(2*3)+(1*2)=91
91 % 10 = 1
So 16424-32-1 is a valid CAS Registry Number.

Identification and synthesis of new volatile molecules found in extracts obtained from distinct parts of cooked chicken

Delort, Estelle,Velluz, Alain,Frerot, Eric,Rubin, Mark,Jaquier, Alain,Linder, Simon,Eidman, Kirk F.,MacDougall, Brian S.

experimental part, p. 11752 - 11763 (2012/04/04)

Several chicken parts (skin, fat, juice) were cooked in different ways (roasting, simmering) and investigated separately for their volatile composition. In-depth GC/MS analysis of the separate fractions revealed several unknown molecules. Mass spectra interpretation allowed us to identify nine molecules for the first time in chicken, including cyclic aldehydes, cyclic ketones, and new δ-lactones containing an unsaturated linear chain. Identification was confirmed by chemical synthesis followed by comparison of the mass spectra and linear retention indices. The natural occurrence of five of these molecules is reported here for the first time in a natural product.

Thioalkylation of Enolates, IV. α-Alkylidenecyclopentanones by α-Alkylidation of Methyl 2-Oxocyclopentanecarboxylate

Arnecke, Ralf,Groth, Ulrich,Koehler, Thomas

, p. 891 - 894 (2007/10/02)

An α-alkylidation of cyclopentanone was achieved in two reaction steps in an overall yield of 20 to 79percent via a zinc chloride-catalyzed thioalkylation of the zinc enolate of methyl 2-oxocyclopentanecarboxylate (3) and subsequent saponification/desulfurization of the β-(phenylthio) ketone intermediates 5.For the saponification/desulfurization step DABCO proved to be the reagent of choice and superior to the use of alkali or magnesium halides. - Key Words: Zinc enolates, thioalkylation of / Cyclopentanones, α-alkylidene

α-ALKYLATION AND α-ALKYLIDENATION OF CARBONYL COMPOUNDS BY O-SILYLATED ENOLATE PHENYLTHIOALKYLATION

Paterson, Ian

, p. 4207 - 4220 (2007/10/02)

For many reactions next to a carbonyl group, the use of O-silylated enolate chemistry offers improvements in yield and selectivity over the corresponding reactions of Group I metal enolates.In the case of α-alkylation of carbonyl compounds, Lewis acid (TiCl4 or ZnBr2) promoted phenylthioalkylation of O-silylated enolates 3 by α-chlorosulphides 4 (R3=H, Me, Prn, Pri, Bui, and Me3Si), followed by reductive sulphur removal by Raney nickel, 5->6, is found to be a reliable method for this synthetically important C-C bond forming step.An alternative sulphur elimination pathway via the sulphoxide, 5->7, allows the regio- and stereocontrolled α-alkylidenation of carbonyl compounds.The phenylthioalkylation reaction is applicable to ketones, aldehydes, esters, and lactones.
