α-L-sorbopyranose-β-L-sorbopyranose 1,2':2,1'-dianhydride is a complex organic compound with the molecular formula C12H14O7. It is a dianhydride derivative of two L-sorbopyranose molecules, which are sugar units. α-L-sorbopyranose-β-L-sorbopyranose 1,2':2,1'-dianhydride is formed by the condensation of two L-sorbopyranose units through the elimination of two water molecules, resulting in the formation of an anhydride bridge between the two sugar units. The specific arrangement of the sugar units in α-L-sorbopyranose-β-L-sorbopyranose 1,2':2,1'-dianhydride is α-L-sorbopyranose linked to β-L-sorbopyranose, with the anhydride bridges connecting the 1,2' and 2,1' positions. α-L-sorbopyranose-β-L-sorbopyranose 1,2':2,1'-dianhydride is of interest in the field of organic chemistry and may have potential applications in the synthesis of complex carbohydrates and other biologically active molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 50692-21-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,6,9 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 50692-21:
(7*5)+(6*0)+(5*6)+(4*9)+(3*2)+(2*2)+(1*1)=112
112 % 10 = 2
So 50692-21-2 is a valid CAS Registry Number.

THE BEHAVIOR OF L-SORBOSE TOWARDS ANHYDROUS HYDROGEN FLUORIDE

Defaye, Jacques,Gadelle, Andree,Pedersen, Christian

, p. 89 - 98 (2007/10/02)

L-Sorbose was converted into a mixture of L-sorbose dianhydrides by treatment with anhydrous hydrogen fluoride.Of the six dianhydrides isolated, two were known compounds.The structures have been established by n.m.r. spectroscopy.The relative amounts of dianhydrides obtained depended on the reaction conditions.By use of 13C-n.m.r. spectroscopy, the reaction of L-sorbose with hydrogen fluoride was shown to involve L-sorbofuranosyl fluoride as an intermediate.Dianhydrides were also formed when L-sorbose was treated with methanol and sulfuric acid under Fischer glycosidation condition, or with trifluoroacetic acid.
