Penta-O-acetyl-1-O-benzyl-1-chlor-1-deoxy-D-galactose-aldehyd is a complex organic compound with the molecular formula C23H27ClO10. It is a derivative of D-galactose, a monosaccharide sugar, where the hydroxyl group at the first carbon has been replaced with a chlorine atom, and the aldehyde group at the same position has been retained. The molecule features a benzyl group attached to the first carbon, which provides steric hindrance and can influence the reactivity of the molecule. Additionally, five acetate groups are acetylated at the remaining hydroxyl groups, which serve to protect these positions from unwanted reactions. Penta-O-acetyl-1-O-benzyl-1-chlor-1-deoxy-D-galactose-aldehyd is significant in organic synthesis, particularly in the preparation of complex carbohydrates and as a building block for the synthesis of various biologically active molecules. Its structure allows for selective deprotection and functionalization, making it a valuable intermediate in the synthesis of more complex molecules.

4356-99-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4356-99-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,5 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.Calculate Digit Verification of CAS Registry Number 4356-99:
(6*4)+(5*3)+(4*5)+(3*6)+(2*9)+(1*9)=104
104 % 10 = 4
So 4356-99-4 is a valid CAS Registry Number.
