Check Digit Verification of cas no
The CAS Registry Mumber 613664-71-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,3,6,6 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 613664-71:
(8*6)+(7*1)+(6*3)+(5*6)+(4*6)+(3*4)+(2*7)+(1*1)=154
154 % 10 = 4

Synthesis of hexasaccharide fragments of pectin
Clausen, Mads H.,Madsen, Robert
, p. 3821 - 3832 (2007/10/03)
Abstract: Short syntheses of partially methyl-esterified hexagalacturonates 1-5 are described as part of the development of strategies for the preparation of larger pectic oligosaccharides. The methodology is based on the repeated coupling of galactose mo
