Check Digit Verification of cas no

The CAS Registry Mumber 1610458-47-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,0,4,5 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1610458-47:
(9*1)+(8*6)+(7*1)+(6*0)+(5*4)+(4*5)+(3*8)+(2*4)+(1*7)=143
143 % 10 = 3
So 1610458-47-3 is a valid CAS Registry Number.

An Interrupted Pummerer/Nickel-Catalysed Cross-Coupling Sequence

Aukland, Miles H.,Talbot, Fabien J. T.,Fernández-Salas, José A.,Ball, Matthew,Pulis, Alexander P.,Procter, David J.

, p. 9785 - 9789 (2018/07/31)

An interrupted Pummerer/nickel-catalysed cross-coupling strategy has been developed and used in the elaboration of styrenes. The operationally simple method can be carried out as a one-pot process, involves the direct formation of stable alkenyl sulfonium salt intermediates, utilises a commercially available sulfoxide, catalyst, and ligand, operates at ambient temperature, accommodates sp-, sp2-, and sp3-hybridised organozinc coupling partners, and delivers functionalised styrene products in high yields over two steps. An interrupted Pummerer/cyclisation approach has also been used to access carbo- and heterocyclic alkenyl sulfonium salts for cross-coupling.

Transition-metal-free semihydrogenation of diarylalkynes: Highly stereoselective synthesis of trans -alkenes using Na2S·9H 2O

Chen, Zhengwang,Luo, Miaoting,Wen, Yuelu,Luo, Guotian,Liu, Liangxian

supporting information, p. 3020 - 3023 (2014/06/23)

A highly stereoselective and efficient transition-metal-free semihydrogenation of internal alkynes to E-alkenes using cheap and green water as hydrogen donor is described. The reactions are conducted under convenient conditions and provide products in good to excellent yields, with broad substrate scope, including a variety of diarylalkynes.
