24890-61-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 24890-61-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,8,9 and 0 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 24890-61:
(7*2)+(6*4)+(5*8)+(4*9)+(3*0)+(2*6)+(1*1)=127
127 % 10 = 7
So 24890-61-7 is a valid CAS Registry Number.

Aryl-Diadamantyl Phosphine Ligands in Palladium-Catalyzed Cross-Coupling Reactions: Synthesis, Structural Analysis, and Application

supporting information, p. 1122 - 1128 (2020/03/03)

Synthesis, temperature-dependent NMR structure investigation and utilization of a new, stable and easily accessible aryl-diadamantylphosphine ligand family is reported. The bulky and electron-rich phosphorus center of the ligand enhances the catalytic activity of palladium in cross-coupling reactions of sterically demanding ortho-substituted aryl halides. In our study, we demonstrated the synthetic applicability of the new phosphine ligands in Buchwald-Hartwig and tosyl hydrazone coupling reactions.
