5-Benzoylamino-O1,O2-isopropylidene-O3-methanesulfonyl-β-D-5-deoxy-arabinofuranose is a complex organic compound with a unique structure. It features a benzoylamino group at the 5-position, an isopropylidene protecting group at the O1 and O2 positions, and a methanesulfonyl protecting group at the O3 position. The compound is derived from β-D-5-deoxy-arabinofuranose, a sugar molecule that lacks an oxygen atom at the 5-position. This chemical is of interest in the field of organic synthesis and carbohydrate chemistry, as it represents a modified sugar with potential applications in the development of pharmaceuticals and other bioactive compounds. The protecting groups present in the molecule are crucial for preventing unwanted reactions at specific functional groups, allowing for selective modification and synthesis of more complex molecules.
The CAS Registry Mumber 7687-68-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,8 and 7 respectively; the second part has 2 digits, 6 and 8 respectively. Calculate Digit Verification of CAS Registry Number 7687-68: (6*7)+(5*6)+(4*8)+(3*7)+(2*6)+(1*8)=145 145 % 10 = 5 So 7687-68-5 is a valid CAS Registry Number.
