55569-66-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55569-66-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,5,6 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 55569-66:
(7*5)+(6*5)+(5*5)+(4*6)+(3*9)+(2*6)+(1*6)=159
159 % 10 = 9
So 55569-66-9 is a valid CAS Registry Number.

Synthesis of linkage-specific sialoside substrates for colorimetric assay of neuraminidases
Kodama,Baum,Paulson
, p. 111 - 119 (1991)
Neuraminidase substrates suitable for analysis of linkage specificity were enzymically synthesized in good yield by linking N-acetylneuraminic acid (Neup5Ac) to O-6 and O-3 of 4-nitrophenyl-β-D-galactopyranoside with β-D-galactoside-α-(2 → 6)-sialyltransf
