290330-46-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 290330-46-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,0,3,3 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 290330-46:
(8*2)+(7*9)+(6*0)+(5*3)+(4*3)+(3*0)+(2*4)+(1*6)=120
120 % 10 = 0
So 290330-46-0 is a valid CAS Registry Number.

A Sialyl-Lewis A-asparagine building block for glycopeptide-synthesis
Peilst?cker, Karen,Kunz, Horst
, p. 820 - 822 (2007/10/03)
Using the azido group as the anomeric protection a Sialyl Lewis A tetrasaccharide was synthesized from N-acetylglucosamine via the type1 lactosamine and Lewis A intermediates. After reduction of the azido group, coupling with Fmoc α-allyl aspartate and Pd
