The chemical compound "O1,O2,O3,O4-tetraacetyl-O6-(tri-O-acetyl-2-benzoylamino-2-deoxy-β-D-glucopyranosyl)-β-D-glucopyranose" is a complex carbohydrate derivative. It features a β-D-glucopyranose sugar unit at the core, with four acetyl groups (O1, O2, O3, O4) protecting the hydroxyl groups at the 1, 2, 3, and 4 positions. Additionally, it has a 6-O-glycosidic linkage to another β-D-glucopyranose unit, which is modified with a 2-benzoylamino-2-deoxy group and three acetyl protecting groups. O1,O2,O3,O4-tetraacetyl-O6-(tri-O-acetyl-2-benzoylamino-2-deoxy-β-D-glucopyranosyl)-β-D-glucopyranose is significant in the field of organic chemistry, particularly in the synthesis of complex glycoconjugates and as a potential intermediate in the preparation of bioactive molecules. Its structure highlights the importance of protecting groups in organic synthesis, which are crucial for preventing unwanted side reactions and ensuring the selective formation of desired products.
The CAS Registry Mumber 4752-94-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,5 and 2 respectively; the second part has 2 digits, 9 and 4 respectively. Calculate Digit Verification of CAS Registry Number 4752-94: (6*4)+(5*7)+(4*5)+(3*2)+(2*9)+(1*4)=107 107 % 10 = 7 So 4752-94-7 is a valid CAS Registry Number.
