199326-63-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 199326-63-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,3,2 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 199326-63:
(8*1)+(7*9)+(6*9)+(5*3)+(4*2)+(3*6)+(2*6)+(1*3)=181
181 % 10 = 1
So 199326-63-1 is a valid CAS Registry Number.

Preparation of 7-alkoxylated furanopyrones: Semisynthesis of (-)- etharvensin, a new styryl-lactone from Goniothalamus arvensis

Bermejo,Blazquez,Serrano,Zafra-Polo,Cortes

, p. 1338 - 1340 (1997)

A new furanopyrone derivative, (-)-etharvensin (1), was isolated from the stem bark of Goniothalamus arvensis. Semisynthesis of the 7- ethoxyfuranopyrone 1 was achieved by addition of EtOH in concentrated acid medium to the unsaturated α-pyrone (+)-althol

Synthesis of (+)-altholactone, (+)-7-epi-altholactone, (?)-etharvensin, and (+)-alumheptolide-A using Pd-catalyzed carbonylation

Miyazawa, Yuki,Hattori, Yasunao,Makabe, Hidefumi

supporting information, p. 4024 - 4027 (2018/10/05)

Syntheses of (+)-altholactone isolated from Goniothalamus giganteus and its C-7 epimer (+)-7-epi-altholactone, (?)-etharvensin and (+)-alumheptolide-A were achieved. The lactone ring of these compounds was constructed using Pd-catalyzed carbonylation.
