4338-42-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4338-42-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,3 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4338-42:
(6*4)+(5*3)+(4*3)+(3*8)+(2*4)+(1*2)=85
85 % 10 = 5
So 4338-42-5 is a valid CAS Registry Number.

SELECTIVE OXIDATION OF CARBOHYDRATES

-

, (2014/01/09)

The invention relates to the field of carbohydrate chemistry. Provided is a process for the regioselective oxidation of a single secondary hydroxy function of a carbohydrate substrate comprising two or more secondary hydroxy functions, comprising contacting the carbohydrate substrate in a solvent in the presence of a transition metal catalyst complex with an oxidizing agent to yield a mono-oxidized carbohydrate.

Practical synthesis of amino-sugars, 4-amino-4-deoxy-D-galactose, 4-amino-4-deoxy-L-arabinose, 3-amino-3-deoxy-D-allose, 3-amino-3-deoxy-D-glucose, 3-amino-3-deoxy-D-ribose, 3-amino-3-deoxy-D-xylose, 2-amino-2-deoxy-D-mannose, and 5-amino-5-deoxy-D-glucos
