781-74-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 781-74-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,8 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 781-74:
(5*7)+(4*8)+(3*1)+(2*7)+(1*4)=88
88 % 10 = 8
So 781-74-8 is a valid CAS Registry Number.

Pd-Catalyzed Regioselective Branched Hydrocarboxylation of Terminal Olefins with Formic Acid

Chu, Jianxiao,Guo, Jianqiong,Ren, Wenlong,Shi, Yian,Shi, Yuan,Wang, Mingzhou,Zhou, Jintao

supporting information, p. 886 - 891 (2022/02/07)

A regioselective Pd-catalyzed hydrocarboxylation of terminal olefins with HCOOH is described. A wide variety of branched carboxylic acids can readily be obtained with high regioselectivities under mild reaction conditions. The reaction is operationally simple and requires no handling of toxic CO. The ligand and LiCl are important factors for reaction reactivity and selectivity.

Pd-Catalyzed Highly Chemo- And Regioselective Hydrocarboxylation of Terminal Alkyl Olefins with Formic Acid

Ren, Wenlong,Chu, Jianxiao,Sun, Fei,Shi, Yian

supporting information, p. 5967 - 5970 (2019/08/26)

An efficient Pd-catalyzed hydrocarboxylation of alkenes with HCOOH is described. A wide variety of linear carboxylic acids bearing various functional groups can be obtained with excellent chemo- and regioselectivities under mild reaction conditions. The reaction process is operationally simple and requires no handling of toxic CO.

Synthesis of 1-tetralone derivatives using a Stille cross coupling/friedel crafts acylation sequence

Vercouillie, Johnny,Abarbri, Mohamed,Parrain, Jean-Luc,Duchene, Alain,Thibonnet, Jerome

, p. 3751 - 3762 (2007/10/03)

An efficient method of synthesis of 1-tetralones has been achieved featuring a Stille cross-coupling reaction as the key step.
