128596-89-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128596-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,9 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128596-89:
(8*1)+(7*2)+(6*8)+(5*5)+(4*9)+(3*6)+(2*8)+(1*9)=174
174 % 10 = 4
So 128596-89-4 is a valid CAS Registry Number.

, p. 139 - 150 (2007/10/02)
Synthesis is described of bifunctional di- and trisaccharide monomers built up of (1-6)-β-linked D-galactofuranose units and carrying 6-O-trityl and 1,2-O-(1-cyano)ethylidene groups at extreme termini.They are converted into cyclic oligosaccharides under
