188860-33-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 188860-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,8,6 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 188860-33:
(8*1)+(7*8)+(6*8)+(5*8)+(4*6)+(3*0)+(2*3)+(1*3)=185
185 % 10 = 5
So 188860-33-5 is a valid CAS Registry Number.

Synthesis of a polymer-supported sialic acid glycosyl donor
Kononov, Leonid O.,Ito, Yukishige,Ogawa, Tomoya
, p. 1599 - 1602 (2007/10/03)
A sialic acid glycosyl donor 9 immobilized on polyethyleneglycol monomethyl ether (MPEG) was prepared. Glycosylation of galactose derivatives 10 or 15 with 9 led to α-linked disaccharides 13 and 16, respectively.
