128238-19-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128238-19-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,2,3 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128238-19:
(8*1)+(7*2)+(6*8)+(5*2)+(4*3)+(3*8)+(2*1)+(1*9)=127
127 % 10 = 7
So 128238-19-7 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
