63124-67-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 63124-67-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,1,2 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 63124-67:
(7*6)+(6*3)+(5*1)+(4*2)+(3*4)+(2*6)+(1*7)=104
104 % 10 = 4
So 63124-67-4 is a valid CAS Registry Number.

Synthesis of quinazoline based chiral ligands and application in the enantioselective addition of phenylacetylene to aldehydes

Karakaya, Idris,Karabuga, Semistan,Altundas, Ramazan,Ulukanli, Sabri

supporting information, p. 8385 - 8388 (2015/03/05)

Five novel 4-phenylquinazolinols were synthesised in three steps. Their application as ligands in the titanium tetraisopropoxide promoted catalytic enantioselective addition of phenylacetylene to a variety of aldehydes gave propargylic alcohols. Under the

Synthesis of phosphine-ligated zinc acetylide dimers: Enhanced reactivity in carbonyl additions

Wilson, Erin E.,Oliver, Allen G.,Hughes, Russell P.,Ashfeld, Brandon L.

experimental part, p. 5214 - 5221 (2011/11/13)

Phosphine-ligated dinuclear zinc acetylides effectively promote the alkynylation of carbonyl derivatives. Good to excellent yields (46-91%) of the corresponding propargylic alcohols were obtained from a wide range of substrates. Crystallographic evidence

Reactivity of 3-silyloxy-1,4-enynes: Gold(III)-catalyzed regioselective nucleophilic substitution

Haug, Timm T.,Harschneck, Tobias,Duschek, Alexander,Lee, Chang-Uk,Binder, J?rg T.,Menz, Helge,Kirsch, Stefan F.

experimental part, p. 510 - 514 (2009/06/05)

Gold-catalyzed reactions of 3-silyloxy-1,4-enynes with alcohols afford primary, secondary, and tertiary pent-2-en-4-ynyl ethers in moderate to excellent yields. The substitution proceeds with high regioselectivity. An initial cyclization providing five-me
