The chemical compound "O4,O5;O6,O7-diisopropylidene-D-gluco-1,2-dideoxy-hept-1-ynitol" is a complex organic molecule derived from a modified sugar structure. It features a D-gluco configuration, indicating that it is based on the D-enantiomer of glucose, a common monosaccharide. The compound is characterized by the absence of two hydroxyl groups (dideoxy) at the 1st and 2nd carbon positions, which is a significant structural alteration. The presence of a hept-1-ynitol group suggests a seven-carbon chain with a hydroxyl group and a triple bond at the first carbon, which can influence the molecule's reactivity and properties. The diisopropylidene group indicates that two isopropyl groups are bridging adjacent hydroxyl groups at the 4th, 5th; and 6th, 7th carbon positions, effectively protecting these hydroxyl groups and altering the molecule's steric properties. O4,O5;O6,O7-diisopropylidene-D-gluco-1,2-dideoxy-hept-1-ynitol is likely to be of interest in organic chemistry, particularly in the synthesis of complex carbohydrates and related structures, due to its unique structural features and potential applications in the development of new pharmaceuticals or materials.
The CAS Registry Mumber 7263-64-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,6 and 3 respectively; the second part has 2 digits, 6 and 4 respectively. Calculate Digit Verification of CAS Registry Number 7263-64: (6*7)+(5*2)+(4*6)+(3*3)+(2*6)+(1*4)=101 101 % 10 = 1 So 7263-64-1 is a valid CAS Registry Number.
