1027256-66-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1027256-66-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,2,5 and 6 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1027256-66:
(9*1)+(8*0)+(7*2)+(6*7)+(5*2)+(4*5)+(3*6)+(2*6)+(1*6)=131
131 % 10 = 1
So 1027256-66-1 is a valid CAS Registry Number.

Stereoselective synthesis of (E)-1-fluoro-1,3-enynes

Yoshida, Masanori,Yoshikawa, Shuhei,Fukuhara, Tsuyoshi,Yoneda, Norihiko,Hara, Shoji

, p. 7143 - 7148 (2001)

1-Fluoro-1,3-enynes were stereoselectively prepared by the cross-coupling reaction of 1-alkynes with β-fluoroalkenyliodides obtained from (β-fluoroalkenyl)iodonium salts. As the reaction proceeds under mild conditions, polyfunctionalized 1-fluoro-1,3-enyn

Regio- and stereoselective synthesis of fluoroalkadienes using β-fluoroalkenyliodonium salt

Yoshida,Nagahara,Fukuhara,Yoneda,Hara

, p. 2283 - 2288 (2007/10/03)

(E,E)-δ-Fluoro-α,β,γ,δ-unsaturated carbonyl compounds and (3E)-4-fluoro-1,3-dienes were stereoselectively synthesized by the palladium-catalyzed coupling reaction of (2-fluoroalkenyl)(p-tolyl)iodonium fluorides with α,β-unsaturated carbonyl compounds and

Stereo- and regioselective synthesis of (E,E)-δ-fluoro-α,β,γ,δ- unsaturated carbonyl compounds by Heck-type reaction of fluoroalkenyliodonium salts

Yoshida, Masanori,Hara, Shoji,Fukuhara, Tsuyoshi,Yoneda, Norihiko

, p. 3887 - 3890 (2007/10/03)

(E,E)-δ-Fluoro-α,β,γ,δ-unsaturated carbonyl compounds were stereo- and regioselectively obtained by a palladium-catalyzed Heck-type reaction of (E)-2-fluoro-1-iodo-1-alkenyliodonium salts with α,β-unsaturated carbonyl compounds. The stereoselective synthesis of the fluorinated analogue of a biologically active unsaturated fatty acid was also achieved using this reaction. (C) 2000 Elsevier Science Ltd.
