Check Digit Verification of cas no

The CAS Registry Mumber 175981-10-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,9,8 and 1 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 175981-10:
(8*1)+(7*7)+(6*5)+(5*9)+(4*8)+(3*1)+(2*1)+(1*0)=169
169 % 10 = 9
So 175981-10-9 is a valid CAS Registry Number.

Synthesis of a thio-linked analogue of sialyl Lewis X

Eisele, Thomas,Toepfer, Alexander,Kretzschmar, Gerhard,Schmidt, Richard R.

, p. 1389 - 1392 (2007/10/03)

Thiolinked sialyl Lewis X analogue 2 was obtained from neuraminic acid, D-galactose, and L-fucose. Galactose was transformed into 3-thiogalactose building block 6 and also into the required 3,4-dithioglucose moiety. Thioglycoside bond formation was performed via base-promoted S-glycosylation [Neu5Acα(2-3S)Gal and Galβ(1-4S)Glc linkages] and via acid catalyzed S-glycosylation [Fucα(1-3S)Glc and Glcβ-(1-1S)heptyl linkages].
