1-Propenyl 2-O-benzoyl-4,6-di-O-benzyl-3-O-tert-butyldimethylsilyl-α-D-galactopyranoside is a complex organic compound that belongs to the class of glycosides. It is derived from galactose, a monosaccharide sugar, and is modified with various functional groups to enhance its chemical properties. The compound features a 1-propenyl group, which is a three-carbon chain with a double bond, attached to the anomeric carbon of the galactopyranose ring. The 2-O position is acylated with a benzoyl group, while the 4-O and 6-O positions are protected with benzyl groups. Additionally, the 3-O position is protected with a tert-butyldimethylsilyl (TBDMS) group, which is a common protecting group in organic synthesis. 1-propenyl 2-O-benzoyl-4,6-di-O-benzyl-3-O-tert-butyldimethylsilyl-α-D-galactopyranoside is of interest in the field of carbohydrate chemistry, particularly for the synthesis of complex oligosaccharides and glycoconjugates, due to its unique structure and the ability to selectively modify the hydroxyl groups of the sugar moiety.

Check Digit Verification of cas no

The CAS Registry Mumber 81726-70-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,7,2 and 6 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81726-70:
(7*8)+(6*1)+(5*7)+(4*2)+(3*6)+(2*7)+(1*0)=137
137 % 10 = 7
So 81726-70-7 is a valid CAS Registry Number.
