(-)-1,2:3,4-di-O-isopropylidene-6-O-methylsulfonyl-α-D-galactopyranose is a complex organic compound derived from α-D-galactopyranose, a monosaccharide sugar. (-)-1,2:3,4-di-O-isopropylidene-6-O-methylsulfonyl-α-D-galactopyranose is characterized by the presence of two isopropylidene groups at the 1,2 and 3,4 positions, which protect the hydroxyl groups and prevent unwanted reactions at these sites. Additionally, a methylsulfonyl group is attached to the 6-O position, further modifying the molecule's reactivity. This specific chemical structure is often used in carbohydrate chemistry for the synthesis of more complex molecules, as the protecting groups can be selectively removed to reveal the underlying hydroxyl groups for further reactions. The compound plays a role in the preparation of various galactose-containing compounds and is a valuable intermediate in organic synthesis, particularly in the pharmaceutical and chemical industries.

4148-55-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4148-55-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,4 and 8 respectively; the second part has 2 digits, 5 and 5 respectively.Calculate Digit Verification of CAS Registry Number 4148-55:
(6*4)+(5*1)+(4*4)+(3*8)+(2*5)+(1*5)=84
84 % 10 = 4
So 4148-55-4 is a valid CAS Registry Number.
