17838-17-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17838-17-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,8,3 and 8 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 17838-17:
(7*1)+(6*7)+(5*8)+(4*3)+(3*8)+(2*1)+(1*7)=134
134 % 10 = 4
So 17838-17-4 is a valid CAS Registry Number.

Pd-catalyzed chemoselective carbonylation of aminophenols with iodoarenes: Alkoxycarbonylation vs aminocarbonylation

Xu, Tongyu,Alper, Howard

, p. 16970 - 16973 (2015/02/02)

Palladium-catalyzed chemoselective carbonylation of aminophenols with iodoarenes was realized by changing ligand and base. 3- or 4-Aminophenols afforded esters in high yields and selectivities using 1,3-bis(diphenylphosphino)propane as the ligand and K2CO3 as the base, and gave amides in high yields and selectivities using 1,3-bis(diisobutylphosphino)propane as the ligand and DBU as the base. 2-Aminophenol only gave amides in high yields under both conditions.
