N-(D-Galactosyl)-p-toluidin, also known as p-toluidinyl-α-D-galactopyranoside, is a chemical compound that consists of a p-toluidine molecule linked to a D-galactose sugar moiety. N-(D-Galactosyl)-p-toluidin is often used as a model substrate in enzymatic reactions, particularly for studying the activity of glycosidases, which are enzymes that cleave glycosidic bonds. The p-toluidine group serves as an aromatic amine that can be easily detected, making it a useful tool for monitoring enzyme activity and kinetics. The compound plays a significant role in biochemical research, particularly in the field of carbohydrate chemistry and enzymology, where it helps to understand the mechanisms of enzyme action and the development of new therapeutic strategies targeting carbohydrate metabolism.
The CAS Registry Mumber 4103-31-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,0 and 3 respectively; the second part has 2 digits, 3 and 1 respectively. Calculate Digit Verification of CAS Registry Number 4103-31: (6*4)+(5*1)+(4*0)+(3*3)+(2*3)+(1*1)=45 45 % 10 = 5 So 4103-31-5 is a valid CAS Registry Number.
