Check Digit Verification of cas no
The CAS Registry Mumber 22509-75-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,5,0 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 22509-75:
(7*2)+(6*2)+(5*5)+(4*0)+(3*9)+(2*7)+(1*5)=97
97 % 10 = 7
So 22509-75-7 is a valid CAS Registry Number.

Use of tunable ligands allows for intermolecular Pd-catalyzed C-O bond formation

Bulky biaryl phosphine ligands facilitate Pd-catalyzed C-O coupling reactions of aryl halides with primary and secondary alcohols by promoting reductive elimination at the expense of β-hydride elimination. The key to their success is the ability to match the size of the ligand to that of the combination of substrates. The efficient coupling of a number of unactivated aryl chlorides and bromides with cyclic and acyclic secondary alcohols was achieved. This included the coupling of allylic alcohols for the first time in a Pd-catalyzed coupling process.
