81739-27-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81739-27-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,7,3 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81739-27:
(7*8)+(6*1)+(5*7)+(4*3)+(3*9)+(2*2)+(1*7)=147
147 % 10 = 7
So 81739-27-7 is a valid CAS Registry Number.

Total Synthesis of Casuarinin

Wakamori, Shinnosuke,Matsumoto, Shintaro,Kusuki, Reina,Ikeuchi, Kazutada,Yamada, Hidetoshi

supporting information, p. 3392 - 3396 (2020/05/22)

This study involves the total synthesis of casuarinin, a naturally occurring ellagitannin, in which an open-chain glucose is esterified with two (S)-hexahydroxydiphenoyl (HHDP) groups. One HHDP group incorporates a C-glycosidic bond between its benzene ring and the glucose moiety, which was constructed with complete stereoselectivity using a benzyl oxime group that opened the glucopyranose ring and acted as a scaffold for C-glycoside production. This total synthesis enables future structure-activity relationship studies of this compound.
