Methyl 3,4-O-(1-methylethylidene)-2-O-(methylsulfonyl)pentopyranoside is a complex organic chemical compound with the molecular formula C12H20O7S. It is a derivative of a pentopyranoside, which is a type of sugar molecule with five carbon atoms in its ring structure. The compound features a methyl group (CH3) attached to the 3rd and 4th carbon atoms through a 1-methylethylidene (isopropylidine) bridge, and a methylsulfonyl group (CH3SO2) attached to the 2nd carbon atom. This specific arrangement of functional groups gives the compound unique chemical properties and potential applications in various fields, such as pharmaceuticals and chemical research.

3945-23-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3945-23-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,4 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3945-23:
(6*3)+(5*9)+(4*4)+(3*5)+(2*2)+(1*3)=101
101 % 10 = 1
So 3945-23-1 is a valid CAS Registry Number.

Regiochemistry of epoxide ring opening in methyl 2,3-anhydro-4-azido-4- deoxy-α- and β-L-lyxopyranosides

Popsavin, Velimir,Benedekovic, Goran,Popsavin, Mirjana,Sreco, Bojana,Djokovic, Dejan

, p. 1866 - 1871 (2007/10/03)

Methyl 2,3-anhydro-4-O-methanesulfonyl-α-D-ribopyranoside (12) was prepared through a new six-step sequence starting from D-arabinose. Chemical behaviour of 12 was further studied under solvolytic conditions and in the presence of azide anion as a nucleophile. Factors governing the regiochemistry of epoxide ring opening are briefly discussed.
