Check Digit Verification of cas no

The CAS Registry Mumber 171820-89-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,8,2 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 171820-89:
(8*1)+(7*7)+(6*1)+(5*8)+(4*2)+(3*0)+(2*8)+(1*9)=136
136 % 10 = 6
So 171820-89-6 is a valid CAS Registry Number.

Direct glycosylation of protected O-tritylserine esters and oligopeptides

Rajca, Andrzej,Wiessler, Manfred

, p. 123 - 136 (2007/10/03)

N-Fmoc-3-O-Tr-L-serine methyl and benzyl esters, as well as a tripeptide FmocAlaSer(Tr)GlyOBn were directly glycosylated by 3,4,6-tri-O-acetyl-1,2-O-(1-cyanoethylidene)-α-D-galactopyranose in the presence of TrClO4 in dichloromethane, yielding 32-57percent of N-Fmoc-3-O-(2,3,4,6-tetra-O-acetyl-β-D-galactopyranosyl)-L-serine esters and the corresponding tripeptide.Keywords: Glycosylation; N-9-Fluorenylmethoxycarbonyl-O-tritylserine esters; Serine glycosides; Serine glycopeptides; Cyanoethylidene condensation
