Check Digit Verification of cas no
The CAS Registry Mumber 139459-55-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,4,5 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 139459-55:
(8*1)+(7*3)+(6*9)+(5*4)+(4*5)+(3*9)+(2*5)+(1*5)=165
165 % 10 = 5
So 139459-55-5 is a valid CAS Registry Number.

Synthesis of mucin O-glycan core structures as their p-nitro- and p-aminophenyl glycosides
Hollinger, Martin,Abraha, Fana,Oscarson, Stefan
experimental part, p. 1454 - 1466 (2011/08/22)
For the investigation of glycosidases, and for the construction of glycan arrays the p-nitrophenyl- and p-aminophenyl glycosides of mucin O-glycan core structures 1-7 and the 2,6-ST-antigen have been chemically synthesized using d-galactose as a precursor for GalNAc residues. GlcNAc residues have partly been introduced using a 4,6-di-O-benzoyl-2,3-N,O-oxazolidinone-protected donor, which allowed deprotection of the formed di- and tri-saccharides in one step using sodium methoxide.
