The chemical "benzyl-(O4-benzyl-O2,O3-isopropylidene-β-L-rhamnopyranoside)" is a complex organic compound with a molecular structure that features a rhamnose sugar moiety. Rhamnose is a type of sugar found in many plants and is known for its biological activities. In this specific compound, the rhamnose is modified with a benzyl group at the O4 position, which is a common protecting group in organic synthesis that can be used to prevent unwanted reactions at that site. Additionally, the O2 and O3 positions of the rhamnose are protected with an isopropylidene group, which is a type of acetal that shields these hydroxyl groups from reacting. The overall structure of benzyl-(O4-benzyl-O2,O3-isopropylidene-β-L-rhamnopyranoside) is designed to protect the rhamnose sugar from unwanted side reactions, which is crucial in the synthesis of more complex molecules, such as glycoconjugates, where precise control over the functional groups is necessary.
The CAS Registry Mumber 4613-14-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,1 and 3 respectively; the second part has 2 digits, 1 and 4 respectively. Calculate Digit Verification of CAS Registry Number 4613-14: (6*4)+(5*6)+(4*1)+(3*3)+(2*1)+(1*4)=73 73 % 10 = 3 So 4613-14-3 is a valid CAS Registry Number.
