Exo-3,4,6-tri-O-acetyl-1,2-O-(tert-butyl orthoacetyl)-α-D-glucopyranose is a complex organic compound derived from α-D-glucopyranose, a monosaccharide. This chemical is characterized by the presence of three acetyl groups attached to the 3rd, 4th, and 6th carbon atoms, and a tert-butyl orthoacetyl group bridging the 1st and 2nd carbon atoms. The acetyl groups are ester derivatives of acetic acid, providing protection to the hydroxyl groups, while the tert-butyl orthoacetyl group is a bulky protecting group that shields the 1st and 2nd hydroxyl groups. exo-3,4,6-tri-O-acetyl-1,2-O-(tert-butyl orthoacetyl)-α-D-glucopyranose is significant in organic synthesis, particularly in the preparation of complex carbohydrates and glycoconjugates, where selective protection and deprotection of hydroxyl groups are crucial for controlling the reaction outcomes. The exo configuration refers to the spatial arrangement of the substituents, which is important for understanding the stereochemistry of the molecule.

4768-77-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4768-77-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,6 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.Calculate Digit Verification of CAS Registry Number 4768-77:
(6*4)+(5*7)+(4*6)+(3*8)+(2*7)+(1*7)=128
128 % 10 = 8
So 4768-77-8 is a valid CAS Registry Number.
