89000-82-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 89000-82-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,0,0 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 89000-82:
(7*8)+(6*9)+(5*0)+(4*0)+(3*0)+(2*8)+(1*2)=128
128 % 10 = 8
So 89000-82-8 is a valid CAS Registry Number.

Furanosyl Oxocarbenium Ion Conformational Energy Landscape Maps as a Tool to Study the Glycosylation Stereoselectivity of 2-Azidofuranoses, 2-Fluorofuranoses and Methyl Furanosyl Uronates

van der Vorm, Stefan,Hansen, Thomas,van Rijssel, Erwin R.,Dekkers, Rolf,Madern, Jerre M.,Overkleeft, Herman S.,Filippov, Dmitri V.,van der Marel, Gijsbert A.,Codée, Jeroen D. C.

supporting information, (2019/04/30)

The 3D shape of glycosyl oxocarbenium ions determines their stability and reactivity and the stereochemical course of SN1 reactions taking place on these reactive intermediates is dictated by the conformation of these species. The nature and co

The Synthesis and Reactivity of Cyclic Thiocarbonates Derived from Some Carbohydrate 1,2-Diols

Patroni, Joseph J.,Stick, Robert V.,Tilbrook, D. Matthew G.,Skelton, Brian W.,White, Allan H.

, p. 2127 - 2141 (2007/10/02)

The attempted synthesis of several carbohydrate 1,2-diols is reported, together with the transformation of two of these diols into cyclic thiocarbonates, namely 4,6-O-benzylidene-3-O-methyl-1,2-O-thiocarbonyl-α-D-glucose and 3,4-O-isopropylidene-1,2-O-thiocarbonyl-β-D-arabinose.The treatment of these thiocarbonates, and a furanose 1,2-thiocarbonate previously prepared by Mukaiyama, with methyl halides and with tributyltin hydride is discussed.A single-crystal X-ray diffraction study of 3,4-O-isopropylidene-1,2-O)-thiocarbonyl-β-D-arabinose is recorded.
