502185-59-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 502185-59-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,2,1,8 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 502185-59:
(8*5)+(7*0)+(6*2)+(5*1)+(4*8)+(3*5)+(2*5)+(1*9)=123
123 % 10 = 3
So 502185-59-3 is a valid CAS Registry Number.

A new stereocontrolled access to β-D-mannopyranosides and 2-acetamido-2-deoxy-β-D-mannopyranosides starting from β-D-galactopyranosides

Attolino, Emanuele,Catelani, Giorgio,D'Andrea, Felicia

, p. 8815 - 8818 (2007/10/03)

A new stereocontrolled synthesis of β-D-mannopyranosides was defined relying on a high yielding sequence based on the following three key steps: (a) a stereospecific inversion at C-2 of β-D-galactopyranosides by an oxidation-reduction procedure; (b) a regiocontrolled formation of 4-deoxy-β-D-threo-hex-3-enopyranosides; (c) a regio- and stereocontrolled hydroboration-oxidation of the above enol ethers. The flexibility of this new method was demonstrated by its extension to the synthesis of 2-acetamido-2-deoxy-β-D-mannopyranosides and of an orthogonally protected β-D-mannopyranoside scaffold and, finally, by the transformation of lactose into the two biologically relevant disaccharides with primary structure β-D-Manp-(1→4)-D-Glc and β-D-ManNAcp-(1→4)-D-Glc.
