Check Digit Verification of cas no

The CAS Registry Mumber 201789-29-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,7,8 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 201789-29:
(8*2)+(7*0)+(6*1)+(5*7)+(4*8)+(3*9)+(2*2)+(1*9)=129
129 % 10 = 9
So 201789-29-9 is a valid CAS Registry Number.

Chemical approach for the syntheses of GM4 isomers with sialic acid to non-natural linkage positions on galactose

Kurimoto, Kenta,Yamamura, Hatsuo,Miyagawa, Atsushi

, p. 39 - 50 (2015/01/08)

Cell-surface glycans containing sialic acid are involved in various biological phenomena. However, the syntheses of GM4 derivatives with (2→2) and (2→4) linkages have not been investigated to date. In this study, sialylation of all of the hydroxyl groups on galactose were investigated for the syntheses of GM4 isomers. Regioselective sialylation was achieved via protection of galactosyl acceptors using electron-rich benzyl groups. These synthetic sialylated glycans will prove to be useful tools for studying unidentified carbohydrate-mediated biological roles.
