Check Digit Verification of cas no

The CAS Registry Mumber 223590-83-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,5,9 and 0 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 223590-83:
(8*2)+(7*2)+(6*3)+(5*5)+(4*9)+(3*0)+(2*8)+(1*3)=128
128 % 10 = 8
So 223590-83-8 is a valid CAS Registry Number.

Approaches to Pyranuronic β-Sugar Amino Acid Building Blocks of Peptidosaccharide Foldamers

Goldschmidt G?z, Viktória,Pintér, István,Harmat, Veronika,Perczel, András

, p. 355 - 361 (2018)

Pyranuronic β-sugar amino acids (β-SAAs) are biocompatible and tuneable building blocks of foldamers and chimera-peptides. The scalable and economical total synthesis of two building blocks is described here. These C-4 epimers, Fmoc-GlcAPU(Me)-OH (7) and

Oxidation of stannylene derivatives of carbohydrates using 1,3-dibromo-5,5-dimethylhydantoin

Soederman, Peter,Widmalm, Goeran

, p. 184 - 186 (2007/10/03)

1,3-Dibromo-5,5-dimethylhydantoin (DBDMH) has been used to oxidize stannylene derivatives of monosaccharides to give hydroxy-ketones thereof. Oxidations could be performed rapidly and in good-to-excellent yields. The oxidizing reagent DBDMH thus provides
