Calculate Digit Verification of CAS Registry Number 142068-31:
(8*1)+(7*4)+(6*2)+(5*0)+(4*6)+(3*8)+(2*3)+(1*1)=103
103 % 10 = 3
So 142068-31-3 is a valid CAS Registry Number.

Efficient [(NHC)Au(NTf2)]-catalyzed hydrohydrazidation of terminal and internal alkynes

Heidrich, Maximillian,Plenio, Herbert

, p. 2080 - 2086 (2020)

The efficient hydrohydrazidation of terminal (6a–r, 18 examples, 0.1–0.2 mol % [(NHC)Au(NTf2)], T = 60 °C) and internal alkynes (7a–j, 10 examples, 0.2–0.5 mol % [(NHC)Au(NTf2)], T = 60–80 °C) utilizing a complex with a sterically demanding bispentiptycenyl-substituted NHC ligand and the benign reaction solvent anisole, is reported.
