669070-52-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 669070-52-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,9,0,7 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 669070-52:
(8*6)+(7*6)+(6*9)+(5*0)+(4*7)+(3*0)+(2*5)+(1*2)=184
184 % 10 = 4
So 669070-52-4 is a valid CAS Registry Number.

Remote stereocontrol in reactions between 4- and 5-alkoxyalk-2- enylstannanes and 1-alkoxycarbonylimines and analogues: Stereoselective approaches to novel α-amino acids

Hallett, David J.,Tanikkul, Nongluk,Thomas, Eric J.

supporting information; experimental part, p. 6130 - 6158 (2012/09/05)

Reactions of the allyltin trichloride 45 generated from (4S)-4-benzyloxypent-2-enyl(tributyl)stannane 1 with imines prepared from glyoxylates proceed with useful levels of 1,5-stereocontrol in favour of (4E)-2,6-anti-2-(alkylamino)-6-benzyloxyhept-4-enoat

Ring-closing metathesis as a key step in the synthesis of 2-pyridones and pyridine triflates

Donohoe, Timothy J.,Fishlock, Lisa P.,Procopiou, Panayiotis A.

experimental part, p. 2665 - 2667 (2009/04/05)

The ring-closing metathesis transformation has been employed to construct a library of functionalized 2-pyridones and pyridine triflates. Using this mild approach, a range of substituent patterns can be built into the aromatic core, including groups which

Palladium-Indium Iodide-Mediated Allylation and Propargylation of Glyoxylic Oxime Ether and Hydrazone: The Role of Water in Directing the Diastereoselective Allylation

Miyabe, Hideto,Yamaoka, Yousuke,Naito, Takeaki,Takemoto, Yoshiji

, p. 1415 - 1418 (2007/10/03)

Allylation and propargylation of glyoxylic oxime ether in the presence of a catalytic amount of palladium(O) complex and indium(I) iodide were studied. Excellent diastereoselectivities in allylation were achieved in the presence of water, although low dia
