512809-21-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 512809-21-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,2,8,0 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 512809-21:
(8*5)+(7*1)+(6*2)+(5*8)+(4*0)+(3*9)+(2*2)+(1*1)=131
131 % 10 = 1
So 512809-21-1 is a valid CAS Registry Number.

Catalytic Asymmetric Synthesis of All Possible Stereoisomers of 2,3,4,6-Tetradeoxy-4-Aminohexopyranosides

Zhu, Zhongpeng,Glazier, Daniel A.,Yang, Daoshan,Tang, Weiping

, p. 2211 - 2215 (2018/06/14)

We recently developed a divergent strategy for the synthesis of all eight possible 2,3,6-trideoxyhexopyranosides with three stereogenic centers. However, the diastereoselectivity for one of the three stereogenic centers was low and it was not controlled b

Chiral Catalyst-Directed Dynamic Kinetic Diastereoselective Acylation of Lactols for de Novo Synthesis of Carbohydrate

Wang, Hao-Yuan,Yang, Ka,Yin, Dan,Liu, Can,Glazier, Daniel A.,Tang, Weiping

, p. 5272 - 5275 (2015/11/18)

The control of the stereochemistry at the anomeric position is still one of the major challenges of synthetic carbohydrate chemistry. We have developed a new strategy consisting of a chiral catalyst-directed acylation followed by a palladium-catalyzed gly

Application of the Wharton rearrangement for the de novo synthesis of pyranosides with ido, manno, and colito stereochemistry

Cuccarese, Michael F.,Wang, Hua-Yu Leo,O'Doherty, George A.

, p. 3067 - 3075 (2013/06/27)

A de novo asymmetric synthesis of α-ido-pyranosides, as well as several deoxy and amino variants, has been achieved. The procedure involves a palladium(0)-catalyzed glycosylation in combination with a Wharton rearrangement/epoxide-opening reaction sequence to access sugars with ido, manno, and colito stereochemistry as well as several azido analogues.
