Methyl 2,3-anhydro-4,6-O-ethylidenehexopyranoside is a complex organic compound with the molecular formula C9H14O4. It is a derivative of a hexopyranoside, which is a type of sugar molecule. The compound features a methyl group attached to the anomeric carbon, and an ethylidene bridge between the 4 and 6 hydroxyl groups, which results in the anhydro structure. This specific arrangement of atoms and functional groups gives the compound unique chemical properties and reactivity. It is often used in organic synthesis, particularly in the preparation of complex carbohydrates and other related biomolecules, due to its ability to serve as a building block for more intricate structures. The compound's anhydro nature and ethylidene bridge contribute to its stability and reactivity, making it a valuable intermediate in the synthesis of various biologically active compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 6743-75-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,4 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 6743-75:
(6*6)+(5*7)+(4*4)+(3*3)+(2*7)+(1*5)=115
115 % 10 = 5
So 6743-75-5 is a valid CAS Registry Number.

, p. 117 - 124 (2015/10/28)

The phenylsulfonylethylidene (PSE) acetal is a relatively new protecting group in carbohydrate chemistry. However, carbohydrate-derived phenylsulfonylethylidene (PSE) acetals show a different behavior in reductive desulfonylation than simple symmetrical a
