70197-34-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 70197-34-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,1,9 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 70197-34:
(7*7)+(6*0)+(5*1)+(4*9)+(3*7)+(2*3)+(1*4)=121
121 % 10 = 1
So 70197-34-1 is a valid CAS Registry Number.

Catalytic conversion of alkynes to α-vinyl sulfides mediated by carbene-linker-carbene (CXC) rhodium and iridium complexes

Tolley, Lewis C.,Fernández, Israel,Bezuidenhout, Daniela I.,Guisado-Barrios, Gregorio

, p. 516 - 523 (2021/02/09)

The catalytic activity of a set of mono- and bimetallic Rh(i) and Ir(i) complexes bearing carbene-linker-carbene (CXC) bis-triazolylidene ligands (with X = O, N) coordinated in a bridging or chelating fashion was evaluated in the hydrothiolation of alkyne

Stereoselective hydrozirconation of alkynylsulfide and regioselective synthesis of haloalkenyl sulfide via electrophile-switched halogenation of thioalkenyl zirconocene

Zheng, Weixin,Hong, Ya,Wang, Ping,Zheng, Fenfen,Zhang, Yanjing,Wang, Wei

supporting information, p. 3643 - 3646 (2013/07/19)

Stereoselective preparation of alkenyl sulfide was carried out via syn-hydrozirconation of the alkynyl sulfide. Regiochemistry of halogenation of the thioalkenyl zirconocene could be switched by different halides. α-Chloroalkenyl sulfide or β-haloalkenyl

Water-promoted regioselective hydrothiolation of alkynes

Bhadra, Sukalyan,Ranu, Brindaban C.

experimental part, p. 1605 - 1609 (2010/04/03)

Water promotes hydrothiolation of unactivated alkynes efficiently without any catalyst or additive. The reaction at room temperature furnishes vinyl sulfides with high regioselectivity via anti-Markovnikov addition. The terminal al- kynes provide dithiola
