Uses

Lactosamine forms the backbone of several cell surface glycans such as sialylated glycans or keratin sulfates. Also, it is a basic structural element of Lewis type, and human milk oligosaccharides.

Definition

ChEBI: A disaccharide that consists of D-glucosamine having a beta-D-galactosyl residue attached at position 4.

Check Digit Verification of cas no

The CAS Registry Mumber 13000-25-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,0,0 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 13000-25:
(7*1)+(6*3)+(5*0)+(4*0)+(3*0)+(2*2)+(1*5)=34
34 % 10 = 4
So 13000-25-4 is a valid CAS Registry Number.
