Check Digit Verification of cas no

The CAS Registry Mumber 10488-95-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,4,8 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 10488-95:
106 % 10 = 6
So 10488-95-6 is a valid CAS Registry Number.

Synthesis of coumarins by Pt-catalyzed hydroarylation of propiolic acids with phenols

Oyamada, Juzo,Kitamura, Tsugio

, p. 6918 - 6925 (2006)

Synthesis of coumarins from phenols and propiolic acids was examined by using a Pt catalyst such as PtCl2/AgOTf, K2PtCl4/AgOTf, and K2PtCl4/AgOAc. Propiolic acid reacted even with less reactive phenols in trifluoroacetic acid to give coumarins and dihydrocoumarins. In the case of substituted propiolic acids, phenylpropiolic acid and 2-octynoic acid, the reactions proceeded selectively to afford coumarins in good to high yields.

One-pot synthesis of β-keto esters and preparation of 3-ketopalmitoyl-CoA

Ko?ak, Urban,Kova?, Andreja,Gobec, Stanislav

, p. 1609 - 1612 (2012)

β-Keto esters were synthesized from acyl chlorides and sodium ethyl acetoacetate in EtOH using a simple one-pot, one-step' method. The deacetylation of α-acetyl β-keto ester to β-keto ester was performed simply, by heating the reaction mixture at reflux for 12 hours, without the addition of additional reagents (e.g., NHl, NH MeOH, or NaOH). One of the β-keto esters prepared using this method was ethyl 3-oxohexadecanoate, a key intermediate in the synthesis of 3-ketopalmitoyl coenzyme A (3-oxohexadecanoyl coenzyme A), a potential substrate of the biologically important enzyme 17β-hydroxysteroid dehydrogenase type 12.

Simple synthesis of enantiomers of 6-hydroxyalkan-4-olides by stereoselective hydrogenation of methyl 4,6-dioxoalkanoates

Schulz, Stefan

, p. 1239 - 1240 (1999)

A simple method for the synthesis of (S,S)- or (R,R)-6-hydroxyalkan-4-olides, components of the pheromonal secretion of the butterfly Idea leuconoe, in high ee by enantioselective hydrogenation of 4,6-diketo esters with a commercial available Ru-BINAP catalyst is described.

Efficient Synthesis of Functionalized β-Keto Esters and β-Diketones through Regioselective Hydration of Alkynyl Esters and Alkynyl Ketones by Use of a Cationic NHC–AuICatalyst

Tarigopula, Chandrahas,Thota, Ganesh Kumar,Balamurugan, Rengarajan

, p. 5855 - 5861 (2016)

Regioselective hydration of α-alkynyl esters and ketones by using a cationic NHC–AuIcatalyst results in β-keto esters and β-diketones, respectively. Controlled release of water in acetone by aldol self-condensation under the reaction conditions makes acetone as better solvent than 1,4-dioxane/water for the hydration of α-alkynyl esters having sensitive ester moieties.

A novel convenient route to the naturally occurring 3-oxoacyl-L-homoserinelactones and related bacterial autoinducers

Dekhane, Mouloud,Douglas, Kenneth T.,Gilbert, Peter

, p. 1883 - 1884 (1996)

The naturally occurring 3-oxohexanoyl-L-homoserinelactone (1a), a bacterial autoinducer has been prepared in 47% overall yield by condensing stable 3-oxohexanoic acid (2), prepared by hydrolysis from the corresponding ester (3), with L-homoserinelactone using hydroxybenzotriazole (HOBT) and dicyclohexylcarbodiimide (DCC) in non-aqueous media.

Non-metal Lewis acid-catalyzed cross-Claisen condensation for β-keto esters

Han, Zhengyu,Huang, Hai,Meng, Fuliang,Yang, Zhenkun,Zhang, Tianyu,Zhou, Dapeng

supporting information, p. 9163 - 9166 (2021/11/16)

In this work, we disclose a new catalytic and highly chemoselective cross-Claisen condensation of esters. In the presence of TBSNTf2 as a non-metal Lewis acid, various esters can undergo cross-Claisen condensation to form β-keto esters which are important building blocks. Compared with the traditional Claisen condensation, this process, employing silyl ketene acetals (SKAs) as carbonic nucleophiles to achieve cross-Claisen condensation, requires mild conditions and has good tolerance of functional groups.
