163069-87-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 163069-87-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,0,6 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 163069-87:
(8*1)+(7*6)+(6*3)+(5*0)+(4*6)+(3*9)+(2*8)+(1*7)=142
142 % 10 = 2
So 163069-87-2 is a valid CAS Registry Number.

Synthesis of an α-(2,3)-sialylated, complex-type undecasaccharide
Seifert, Joachim,Lergenmueller, Matthias,Ito, Yukishige
, p. 531 - 534 (2007/10/03)
Only two building blocks were necessary to provide efficient access to the complex undecasaccharide 1 by means of two stereo- and regioselective glycosylation reactions. Stereocontrolled p-methoxybenzyl-assisted β- mannosylation afforded the critical β-ma
