929903-50-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 929903-50-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,9,9,0 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 929903-50:
(8*9)+(7*2)+(6*9)+(5*9)+(4*0)+(3*3)+(2*5)+(1*0)=204
204 % 10 = 4
So 929903-50-4 is a valid CAS Registry Number.

Studies on the zirconium-mediated alkyne-aldehyde coupling reactions: a facile synthesis of stereodefined allylic alcohols and (Z)-2-en-4-yn-1-ols

Guo, Shenghai,Zhang, Hao,Song, Feijie,Liu, Yuanhong

, p. 2009 - 2018 (2007)

An improved zirconium-mediated alkyne-aldehyde cross-coupling reaction has been achieved to afford the stereodefined (Z)-allylic alcohols or 3-iodinated allylic alcohols selectively via protonolysis or iodinolysis of the corresponding five-membered oxazirconacycles. This method has also been successfully applied to the synthesis of (Z)-enynols through cross-coupling reactions of three different components involving alkyne, aldehyde, and alkynyl bromide in a one-pot procedure.

Chemoenzymatic dynamic kinetic resolution of allylic alcohols: A highly enantioselective route to acyloin acetates

Bogar, Krisztian,Vidal, Pilar Hoyos,Alcantara Leon, Andres R.,Baeckvall, Jan-E.

, p. 3401 - 3404 (2008/02/12)

Dynamic kinetic resolution (DKR) of a series of sterically hindered allylic alcohols has been conducted with Candida antarctica lipase B (CALB) and ruthenium catalyst 1. The optically pure allylic acetates obtained were subjected to oxidative cleavage to
