1-Propenyl 2,4-di-O-benzoyl-3,6-di-O-benzyl-α-D-galactopyranoside is a complex organic compound that belongs to the class of glycosides. It is a derivative of α-D-galactopyranose, a monosaccharide sugar, with specific modifications to its hydroxyl groups. The compound features a propenyl group attached to the anomeric carbon (the first carbon in the sugar ring), which is crucial for its reactivity and potential applications in organic synthesis. The 2 and 4 positions of the sugar ring are each acylated with a benzoyl group, which are aromatic ketone moieties derived from benzoic acid. These benzoyl groups protect the hydroxyl groups at these positions from unwanted reactions. Additionally, the 3 and 6 positions are each substituted with a benzyl group, which is a phenylmethyl group derived from benzene. 1-propenyl 2,4-di-O-benzoyl-3,6-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 biologically active molecules due to its protected and functionalized nature.

Check Digit Verification of cas no

The CAS Registry Mumber 78878-38-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,8,7 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 78878-38:
(7*7)+(6*8)+(5*8)+(4*7)+(3*8)+(2*3)+(1*8)=203
203 % 10 = 3
So 78878-38-3 is a valid CAS Registry Number.
