General Description
2-amino-2-deoxy-β-D-glucopyranosyl-(1->4)-2-amino-2-deoxy-β-D-glucopyranose is a chemical compound consisting of two amino groups and two glucose molecules connected in a specific arrangement. It is a type of disaccharide formed by the linkage of two glucose units via a 1->4 glycosidic bond. 2-amino-2-deoxy-β-D-glucopyranosyl-(1->4)-2-amino-2-deoxy-β-D-glucopyranose is often found in naturally occurring polysaccharides such as chitin, a major component of the exoskeletons of crustaceans and insects, as well as in the cell walls of fungi. It is also used in the synthesis of various pharmaceuticals and biologically active compounds due to its unique structure and properties.
Check Digit Verification of cas no
The CAS Registry Mumber 77224-08-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,2 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77224-08:
(7*7)+(6*7)+(5*2)+(4*2)+(3*4)+(2*0)+(1*8)=129
129 % 10 = 9
So 77224-08-9 is a valid CAS Registry Number.

, p. 137 - 144 (2007/10/03)
Two chitosans with widely different chemical composition (fraction of N-acetylated units (FA) A = 0.59), were degraded by nitrous acid, to obtain the reactive 2,5-anhydro-D-mannose- (M-) unit at the new reducing end. The
