273720-79-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 273720-79-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,3,7,2 and 0 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 273720-79:
(8*2)+(7*7)+(6*3)+(5*7)+(4*2)+(3*0)+(2*7)+(1*9)=149
149 % 10 = 9
So 273720-79-9 is a valid CAS Registry Number.

Synthesis of E- and Z-o-methoxy-substituted 2,3-diphenyl propenoic acids and its methyl esters

Felfoeldi, Karoly,Sutyinszky, Maria,Nagy, Nora,Palinko, Istvan

, p. 1543 - 1553 (2000)

A series of stereoisomeric o-methoxy-substituted 2,3-diphenyl propenoic acids and their methyl esters have been synthesized. The E isomers were prepared by a modified Perkin condensation (substituted benzaldehyde, phenylacetic acid, Et3N/acetic anhydride). The difficult to access Z isomers were obtained conveniently in good yields when the appropriate coumarin derivatives were allowed to react with KOH and CH3I in DMSO.

The Oxidation of (E)-α-Phenylcinnamic Acids with Manganese(III) Acetate

Oishi, Kazuki,Kurosawa, Kazu

, p. 179 - 184 (2007/10/02)

The oxidation of eight (E)-α-phenylcinnamic acids with manganese(III) acetate in boiling acetic acid containing acetic anhydride gave 3-phenylcoumarins, 3-phenyl-1-oxaspirodeca-3,7,9-triene-2,6-diones, 2-phenylbenzofurans, 3-(acetoxymethyl)-2-phenylbenzofurans, 3-formyl-2-phenylbenzofuran, 2-acetoxy-2-phenyl-3(2H)-benzofuranones, (Z)-Α-acetoxystilbenes, 2-acetoxy-1,2-diphenylethanones, 5-acetoxy-4,5-diphenyl-2(5H)-furanones, and diphenylacetylene.Tha reaction pathways are discussed.
