19942-80-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19942-80-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,4 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 19942-80:
(7*1)+(6*9)+(5*9)+(4*4)+(3*2)+(2*8)+(1*0)=144
144 % 10 = 4
So 19942-80-4 is a valid CAS Registry Number.

Palladium catalyzed coupling of aryl chlorides with arylboronic acids
Shen, Wang
, p. 5575 - 5578 (1997)
Aryl chlorides bearing electron withdrawing groups were successfully coupled with arylboronic acids (Suzuki reaction). Two palladium catalyst ligands, tricyclohexylphosphine (PCy3) and 1,3-bis(diphenylphosphino)propane (dppp), were found to be superior in catalyzing the reaction.
