The chemical compound "O2,O5-bis-(4-nitro-benzoyl)-β-D-erythro-3-deoxy-pentofuranosyl bromide" is a complex organic molecule with a unique structure. It features a pentofuranosyl core, which is a type of sugar molecule, with a β-D-erythro configuration, indicating the specific arrangement of its carbon atoms. The molecule is further modified by the presence of two 4-nitro-benzoyl groups, which are attached to the oxygen atoms at positions 2 and 5, and a bromine atom at the 3-deoxy position, which replaces the hydroxyl group typically found in pentofuranosides. O2,O5-bis-(4-nitro-benzoyl)-β-D-erythro-3-deoxy-pentofuranosyl bromide is likely used in advanced chemical research, particularly in the synthesis of complex organic molecules or as an intermediate in the preparation of pharmaceuticals. Its specific applications may include the study of sugar chemistry, the development of new drugs, or as a tool in organic synthesis.
The CAS Registry Mumber 7057-29-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,5 and 7 respectively; the second part has 2 digits, 2 and 9 respectively. Calculate Digit Verification of CAS Registry Number 7057-29: (6*7)+(5*0)+(4*5)+(3*7)+(2*2)+(1*9)=96 96 % 10 = 6 So 7057-29-6 is a valid CAS Registry Number.
