97747-56-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 97747-56-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,7,4 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 97747-56:
(7*9)+(6*7)+(5*7)+(4*4)+(3*7)+(2*5)+(1*6)=193
193 % 10 = 3
So 97747-56-3 is a valid CAS Registry Number.

NINE PHENETHYL ALCOHOL GLYCOSIDES FROM STACHYS SIEBOLDII

Nishimura, Hiroaki,Sasaki, Hiroshi,Inagaki, Nobuyuki,Chin, Masao,Zhengxiong, Chen,Mitsuhashi, Hiroshi

, p. 965 - 969 (1991)

Three new phenethyl alcohol glycosides together with six known compounds have been isolated from the leaves of Stachys sieboldii.On the basis of chemical and spectral analyses, the structures of three new compounds named stachysosides A, B and C have been established as 2-(3,4-dihydroxyphenyl)ethyl O-α-L-arabinopyranosyl-(1->2)-α-L-rhamnopyranosyl-(1->3)-4-O-E-caffeoyl-β-D-glucopyranoside, 2-(3,4-dihydroxyphenyl)ethyl O-α-L-arabinopyranosyl-(1->2)-α-L-rhamnopyranosyl-(1->3)-4-O-E-feruloyl-β-D-glucopyranoside and 2-(3-hydroxy-4-methoxyphenyl)ethyl O-α-L-arabinopranosyl-(1->2)-α-L-rhamnopyranosyl-(1->3)-4-O-E-feruloyl-β-D-glucopyranoside, respectively.

An Approach to the Synthesis of Electron-Rich and Hindered Esters and Its Application to the Synthesis of Acteoside

Zhang, Xiaojuan,Yang, Yutong,Wang, Fuye,Zhou, Zhengbing,Zhang, Hongbin,Zhu, Yugen

supporting information, p. 9210 - 9215 (2021/11/30)

Electron-rich esters are ubiquitously distributed in natural products and play a central role in bioactivities. Herein, we disclose an efficient, mild, and general esterification approach to the synthesis of these esters by employing gold(I)-catalyzed acylation reaction with alkyne-tethered mixed anhydrides and alcohols. This method can be applied to ester-bond formation in complex substrates and facilitates efficient synthesis of acteoside, which belongs to the family of phenylethanoid glycosides and possesses a broad range of bioactivities.
