434957-24-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 434957-24-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,4,9,5 and 7 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 434957-24:
(8*4)+(7*3)+(6*4)+(5*9)+(4*5)+(3*7)+(2*2)+(1*4)=171
171 % 10 = 1
So 434957-24-1 is a valid CAS Registry Number.

Preparation of highly substituted (β-acylamino)acrylates via iron-catalyzed alkoxycarbonylation of N-vinylacetamides with carbazates

Ding, Ran,Zhang, Qiu-Chi,Xu, Yun-He,Loh, Teck-Peng

supporting information, p. 11661 - 11664 (2015/05/20)

An efficient iron(ii)-catalyzed alkoxycarbonylation reaction between N-vinylacetamides and carbazates is reported. The corresponding useful highly substituted (β-acylamino)acrylates could be obtained in reasonable to good yields and stereoselectivity under mild reaction conditions. This journal is

Stereoselective synthesis of highly substituted enamides by an oxidative heck reaction

Liu, Yu,Li, Dan,Park, Cheol-Min

supporting information; experimental part, p. 7333 - 7336 (2011/10/03)

Functionalization of enamides under Heck conditions has been limited to those with unsubstituted vinyl groups. By tuning reaction parameters that allow for the balance between stability and reactivity of reactants, the oxidative Heck cross-coupling to produce highly substituted enamides in good to excellent yields was achieved (see scheme).
