Calculate Digit Verification of CAS Registry Number 1126639-04:
(9*1)+(8*1)+(7*2)+(6*6)+(5*6)+(4*3)+(3*9)+(2*0)+(1*4)=140
140 % 10 = 0
So 1126639-04-0 is a valid CAS Registry Number.

Palladium-catalyzed cross-coupling reactions of 1,2-diiodoalkenes with terminal alkynes: Selective synthesis of unsymmetrical buta-1,3-diynes and 2-ethynylbenzofurans

Liang, Yun,Tao, Li-Ming,Zhang, Yue-Hua,Li, Jin-Heng

, p. 3988 - 3994 (2008)

(E)-1,2-Diiodoalkenes were found to be effective building blocks for the preparation of unsymmetrical buta-1,3-diynes and 2-ethynylbenzofurans. In the presence of palladium(II) acetate and copper(I) iodide, unsymmetrical buta-1,3-diynes were selectively o
