128657-58-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 128657-58-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,6,5 and 7 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 128657-58:
(8*1)+(7*2)+(6*8)+(5*6)+(4*5)+(3*7)+(2*5)+(1*8)=159
159 % 10 = 9
So 128657-58-9 is a valid CAS Registry Number.

Ultrasonication-Assisted Synthesis of a d-Glucosamine-Based β-CD Inclusion Complex and Its Application as an Aqueous Heterogeneous Organocatalytic System

Rani, Dhiraj,Sethi, Aaftaab,Kaur, Khushwinder,Agarwal, Jyoti

, p. 9548 - 9557 (2020/09/09)

For the first time, an inclusion complex has been crafted between a carbohydrate-based molecule and a β-cyclodextrin (CD) hydrophobic cavity for asymmetric catalytic applications. This novel d-glucosamine-based inclusion compound has been synthesized in h

Preparation and use of synthetic monosaccharides, disaccharides, trisaccharides, tetrasaccharides and pentasaccharides useful for the preparation of synthetic heparinoids.

D-Glucosamine as a novel chiral auxiliary for the stereoselective synthesis of P-stereogenic phosphine oxides

D'Onofrio,Copey,Jean-Gérard,Goux-Henry,Pilet,Andrioletti,Framery

, p. 9029 - 9034 (2015/09/01)

D-Glucosamine was successfully employed as a chiral auxiliary for the enantioselective synthesis of phosphine oxides. The influence of the anomeric position was also investigated and revealed the excellent ability of the α-anomer to perform this transform
