400736-44-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 400736-44-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,0,7,3 and 6 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 400736-44:
(8*4)+(7*0)+(6*0)+(5*7)+(4*3)+(3*6)+(2*4)+(1*4)=109
109 % 10 = 9
So 400736-44-9 is a valid CAS Registry Number.

Total synthesis of apoptolidin A

Crimmins, Michael T.,Christie, Hamish S.,Long, Alan,Chaudhary, Kleem

, p. 831 - 834 (2009)

A highly convergent, enantioselective total synthesis of the potent antitumor agent apoptolidin A has been completed. The key transformations include highly selective glycosylations to attach the C27 disaccharide and the C9 6'-deoxy-L-glucose, a cross-met

Total Synthesis of Apoptolidin: Construction of Enantiomerically Pure Fragments

Nicolaou,Fylaktakidou, Konstantina C.,Monenschein, Holger,Li, Yiwei,Weyershausen, Bernd,Mitchell, Helen J.,Wei, Heng-Xu,Guntupalli, Prasuna,Hepworth, David,Sugita, Kazuyuki

, p. 15433 - 15442 (2007/10/03)

A general strategy for the total synthesis of the antitumor agent apoptolidin (1) is proposed, and the chemical synthesis of the defined key building blocks (4, 5, 6, 8, and 9) in their enantiomerically pure forms is described. The projected total synthes

Total synthesis of apoptolidin: Part 1. Retrosynthetic analysis and construction of building blocks

Nicolaou,Li, Yiwei,Fylaktakidou, Konstantina C.,Mitchell, Helen J.,Wei, Heng-Xu,Weyershausen, Bernd

, p. 3849 - 3854 (2007/10/03)

No less than 30 stereogenic elements, a highly unsaturated 20-membered macrocyclic system, four carbohydrate units, and unique biological activity, make the natural occurring apoptolidin (1) a challenging synthetic target. The retrosynthetic analysis reve
