Check Digit Verification of cas no

The CAS Registry Mumber 42308-34-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,3,0 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 42308-34:
(7*4)+(6*2)+(5*3)+(4*0)+(3*8)+(2*3)+(1*4)=89
89 % 10 = 9
So 42308-34-9 is a valid CAS Registry Number.

Decarboxylation of α,β-unsaturated aromatic lactones: Synthesis of: E-ortho -hydroxystilbenes from 3-arylcoumarins or isoaurones

Huang, Xihua,Liu, Jie,Sheng, Jianfei,Song, Xianheng,Du, Zhibo,Li, Mingkang,Zhang, Xuejing,Zou, Yong

supporting information, p. 804 - 808 (2018/03/06)

A simple and environmentally friendly strategy for the synthesis of E-ortho-hydroxystilbenes has been established. Two kinds of α,β-unsaturated aromatic lactones, i.e. the 3-arylcoumarins and the isoaurones, could both readily undergo a cascade hydrolyzation/decarboxylation reaction in the presence of KOH in ethylene glycol to afford the desired E-ortho-hydroxystilbenes in moderate to high yields.

Synthesis of 3-arylcoumarins by FeCL3-promoted cyclization of orto-methoxy-substituted (E)-2,3-diphenylpropenoic acids or their methyl esters

Ge,Fang,Qian

, p. 12 - 18 (2014/05/06)

3-Arylcoumarins were conveniently synthesized in excellent yields by an iron(III) chloride-promoted tandem reaction using methoxy-substituted (E)-2,3-diphenylpropenoic acids or their methyl esters. The structure of 3-(4-methoxyphenyl)coumarin was establis

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.
