Check Digit Verification of cas no

The CAS Registry Mumber 495-32-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,9 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 495-32:
(5*4)+(4*9)+(3*5)+(2*3)+(1*2)=79
79 % 10 = 9
So 495-32-9 is a valid CAS Registry Number.

A simple and efficient approach for the preparation of dihydroxanthyletin, xanthyletin, decursinol and marmesin

Kommera, Rajkumar,Bhimapaka, China Raju

, p. 3204 - 3211 (2020/08/05)

A simple and efficient approach has been developed for the preparation of coumarin natural products such as dihydroxanthyletin, xanthyletin, decursinol and marmesin starting from commercially available 2,4-dihydroxybenzaldehyde with very good yields. Wittig homologation and Claisen rearrangement are the protocols used to achieve these molecules.

Synthesis of coumarin derivatives and their cytoprotective effects on t-BHP-induced oxidative damage in HepG2 cells

Ando, Tomomi,Nagumo, Mina,Ninomiya, Masayuki,Tanaka, Kaori,Linhardt, Robert J.,Koketsu, Mamoru

, p. 2422 - 2425 (2018/06/20)

Coumarins are ubiquitous in higher plants and exhibit various biological actions. The aim of this study was to investigate the structure-activity relationships of coumarin derivatives on tert-butyl hydroperoxide (t-BHP)-induced oxidative damage in human hepatoma HepG2 cells. A series of coumarin derivatives were prepared and assessed for their cytoprotective effects. Among these, a caffeoyl acid-conjugated dihydropyranocoumarin derivative, caffeoyllomatin, efficiently protected against cell damage elicited by t-BHP. Our findings suggest that caffeoyllomatin appears to be a potent cytoprotective agent.

Asymmetric synthesis of 2-Substituted dihydrobenzofurans and 3-hydroxydihydrobenzopyrans through the enantioselective epoxidation of O-silyl-protected ortho-allylphenols

Jiang, Hang,Sugiyama, Takaya,Hamajima, Akinari,Hamada, Yasumasa

, p. 155 - 162 (2011/03/22)

The Shi-type epoxidation of O-tert-butyldiphenylsilyl (TBDPS) protected o-allylphenols serves as an efficient strategy to construct the dihydrobenzofurans and dihydrobenzopyrans in up to 97% ee. This methodology led to the enantioselective synthesis of (+)-marmesin, (-)-(3′R)-decursinol, and (+)-lomatin.
