Check Digit Verification of cas no

The CAS Registry Mumber 188302-05-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,3,0 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 188302-05:
(8*1)+(7*8)+(6*8)+(5*3)+(4*0)+(3*2)+(2*0)+(1*5)=138
138 % 10 = 8
So 188302-05-8 is a valid CAS Registry Number.

Chemoenzymatic synthesis of Galα1-3Gal, Galα1-3Galβ1-4GlcNAc, and their PEG-conjugates

Matsuo, Ichiro,Fujimoto, Hiroshi,Isomura, Megumi,Ajisaka, Katsumi

, p. 255 - 258 (1997)

Galα1-3Gal-pNP was prepared enzymatically from Gal-pNP using α-galactosidase from coffee beans. PEG was attached after the reduction of nitro group into amino group to give Galα1-3Gal-PEG conjugate. After removing the pNP group in Galα1-3Gal-pNP, the obtained disaccharide was used for the synthesis of Galα1-3Galβ1-4GlcNAc and corresponding trisaccharide-PEG conjugate.
