165397-91-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 165397-91-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,5,3,9 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 165397-91:
(8*1)+(7*6)+(6*5)+(5*3)+(4*9)+(3*7)+(2*9)+(1*1)=171
171 % 10 = 1
So 165397-91-1 is a valid CAS Registry Number.

Synthesis of trisaccharide repeating unit of fucosylated chondroitin sulfate

He, Haiqing,Chen, Dong,Li, Xiaomei,Li, Chengji,Zhao, Jin-Hua,Qin, Hong-Bo

supporting information, p. 2877 - 2882 (2019/03/21)

We described the chemical synthesis of a sulfated trisaccharide repeating unit of fucosylated chondroitin sulfate (FCS), which has significant anticoagulant activity. Well-functionalized monosaccharides were readily prepared, and highly efficient glycosyl

Synthesis of a unique trisaccharide having an acetal linkage between open-chain and cyclic sugar found in the cell wall of Proteus

Mukherjee, Chinmoy,Misra, Anup Kumar

experimental part, p. 2746 - 2751 (2009/04/07)

The first stereoselective synthesis of a unique trisaccharide containing an open-chain glycosyl cyclic acetal moiety found in the cell wall of Proteus has been successfully achieved. Most of the intermediate steps are high yielding and highly reproducible. The acetal linkage of the open-chain d-galactosamine moiety with an (S)-configuration was formed exclusively.
