Check Digit Verification of cas no

The CAS Registry Mumber 132364-23-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,3,6 and 4 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 132364-23:
(8*1)+(7*3)+(6*2)+(5*3)+(4*6)+(3*4)+(2*2)+(1*3)=99
99 % 10 = 9
So 132364-23-9 is a valid CAS Registry Number.

Khatun, Sanjida,Mainkar, Prathama Satyendra,Chandrasekhar, Srivari

, p. 717 - 722 (2014/07/07)

Synthesis of C11-C23 fragment of an antitumor natural product, Pladienolide B, in gram-scale, is described. The key steps involved in this synthesis are Julia-Kocienski olefination, opening of epoxide with TBSOTf to form the corresponding - OTBS protected

Synthesis of optically active β- Or γ-alkyl-substituted alcohols through copper-catalyzed asymmetric allylic alkylation with organolithium reagents

Guduguntla, Sureshbabu,Fananas-Mastral, Martin,Feringa, Ben L.

, p. 8274 - 8280 (2013/09/24)

An efficient one-pot synthesis of optically active β-alkyl-substituted alcohols through a tandem copper-catalyzed asymmetric allylic alkylation (AAA) with organolithium reagents and reductive ozonolysis is presented. Furthermore, hydroboration-oxidation following the Cu-catalyzed AAA leads to the corresponding homochiral γ-alkyl-substituted alcohols.

Asymmetric synthesis of the fully elaborated pyrrolidinone core of oxazolomycin A

Donohoe, Timothy J.,O'Riordan, Timothy J. C.,Peifer, Manuel,Jones, Christopher R.,Miles, Timothy J.

, p. 5460 - 5463,4 (2012/12/12)

The asymmetric synthesis of the key pyrrolidinone core, including a highly elaborated exocyclic carbon chain, of the γ-lactam β-lactone antibiotic oxazolomycin A is described. Principal features include the Birch reduction of an aromatic pyrrole nucleus, a late stage RuO4 catalyzed pyrrolidine oxidation, and a highly diastereoselective organocerium addition to an aldehyde.

Total synthesis of the potent antitumor macrolides pladienolide B and D

Kanada, Regina M.,Itoh, Daisuke,Nagai, Mitsuo,Niijima, Jun,Asai, Naoki,Mizui, Yoshiharu,Abe, Shinya,Kotake, Yoshihiko

, p. 4350 - 4355 (2008/03/12)

Getting cross: The total syntheses of two pladienolides (see picture), which have prominent antitumor activity based on a unique mechanism of action, have been accomplished, and their absolute configurations were verified. The 12-membered aliphatic macrolide structure was formed by ring-closing metathesis, and the side-chain moiety was coupled to the macrolide by Julia-Kocienski olefination or cross-metathesis.

Synthesis of optically active bifunctional building blocks through enantioselective copper-catalyzed allylic alkylation using Grignard reagents

Van Zijl, Anthoni W.,Lopez, Fernando,Minnaard, Adriaan J.,Feringa, Ben L.

, p. 2558 - 2563 (2007/10/03)

Enantioselective copper-catalyzed allylic alkylations were performed on allylic bromides with a protected hydroxyl or amine functional group using several Grignard reagents and Taniaphos L1 as a ligand. The terminal olefin moiety in the products was transformed into various functional groups without racemization, providing facile access to a variety of versatile bifunctional chiral building blocks.

Total synthesis of ( - )-cylindrocyclophanes A and F exploiting the reversible nature of the olefin cross metathesis reaction

Smith III,Adams,Kozmin,Paone

, p. 5925 - 5937 (2007/10/03)

Efficient total syntheses of the C2-symmetric ( - )-cylindrocyclophanes A and F (1a and 1f) have been achieved. The initial strategy featured the use of a common advanced intermediate to assemble in stepwise fashion the required macrocycle of 1f, exploiting in turn a Myers reductive coupling followed by ring-closing metathesis. In a second-generation strategy, a remarkable cross olefin metathesis dimerization cascade was discovered and exploited to assemble the requisite [7,7]-paracyclophane macrocycles of both 1a and 1f from dienyl monomers. The successful syntheses also featured the effective use of the Danheiser annulation to construct substrates for both the Myers reductive coupling and the metathesis dimerizations strategies. Finally, the Kowalski two-step chain homologation of esters to siloxyalkynes proved superior over the original one-step protocol.
