1-Propenyl 2,3-di-O-benzoyl-4,6-di-O-benzyl-α-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 various disaccharides and polysaccharides. This specific compound features a galactopyranose ring, which is a six-carbon sugar structure. The α-D-galactopyranoside notation indicates that the galactose is in its alpha anomer form and is in the D-configuration, which refers to the spatial arrangement of the hydroxyl groups on the chiral carbon atoms. The compound is further modified with protective groups: two benzoyl groups are attached to the 2nd and 3rd hydroxyl groups, and two benzyl groups are attached to the 4th and 6th hydroxyl groups. These protective groups are commonly used in organic synthesis to prevent unwanted reactions at specific sites on the sugar molecule. The 1-propenyl group indicates the presence of a propenyl (allyl) moiety attached to the first carbon of the galactopyranose ring. 1-propenyl 2,3-di-O-benzoyl-4,6-di-O-benzyl-α-D-galactopyranoside is often used in the synthesis of more complex carbohydrates and as a building block in the preparation of various biologically active molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 81713-17-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,7,1 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81713-17:
(7*8)+(6*1)+(5*7)+(4*1)+(3*3)+(2*1)+(1*7)=119
119 % 10 = 9
So 81713-17-9 is a valid CAS Registry Number.
