Tetra-O-acetyl-S-ethoxythiocarbonyl-β-D-1-thio-mannopyranose is a complex organic compound that belongs to the class of glycosides. It is a derivative of β-D-mannopyranose, a monosaccharide, with a sulfur atom replacing the oxygen atom at the anomeric position, forming a thioglycoside. The molecule is further modified by the addition of four acetyl groups (-COCH3) attached to the hydroxyl groups at the 2, 3, 4, and 6 positions of the mannopyranose ring, and an ethoxythiocarbonyl group (-C(S)SCH2CH3) at the anomeric position. tetra-O-acetyl-S-ethoxythiocarbonyl-β-D-1-thio-mannopyranose is often used in organic synthesis and carbohydrate chemistry, particularly in the preparation of complex glycoconjugates and as a protecting group in the synthesis of oligosaccharides. Its structure provides a stable and reactive intermediate for further chemical modifications, making it a valuable tool in the field of glycobiology and drug development.

Check Digit Verification of cas no

The CAS Registry Mumber 4490-94-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,9 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4490-94:
(6*4)+(5*4)+(4*9)+(3*0)+(2*9)+(1*4)=102
102 % 10 = 2
So 4490-94-2 is a valid CAS Registry Number.

A novel approach for the formation of carbon-nitrogen bonds: Azidation of alkyl radicals with sulfonyl azides

Ollivier,Renaud

, p. 4717 - 4727 (2007/10/03)

Two preparatively attractive methods for the azidation of alkyl radicals are described. Secondary and tertiary alkyl iodides and dithiocarbonates are easily converted into the corresponding azides, either by reaction with ethanesulfonyl azide in the prese
