3-methylphenyl-tetra-O-acetyl-β-D-galactopyranoside is a complex organic compound that belongs to the class of glycosides. It is derived from the sugar galactose, which is a component of many carbohydrates, including lactose. In this specific compound, the galactose molecule is in its β-D configuration, meaning it has a specific three-dimensional arrangement. The term "tetra-O-acetyl" indicates that four hydroxyl groups (-OH) of the galactose have been replaced with acetyl groups (-COCH3), which are derived from acetic acid. This process of acetylation is often used in chemistry to protect hydroxyl groups from unwanted reactions. The "3-methylphenyl" part of the name refers to a phenyl ring (a benzene ring) with a methyl group (-CH3) attached at the third carbon position. 3-methylphenyl-tetra-O-acetyl-β-D-galactopyranoside is often used in organic synthesis and as a building block for the preparation of more complex molecules, particularly in the field of carbohydrate chemistry. It is also of interest in the study of enzyme specificity and as a potential intermediate in the synthesis of pharmaceuticals and other bioactive compounds.

2818-53-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2818-53-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,1 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.Calculate Digit Verification of CAS Registry Number 2818-53:
(6*2)+(5*8)+(4*1)+(3*8)+(2*5)+(1*3)=93
93 % 10 = 3
So 2818-53-3 is a valid CAS Registry Number.
