71639-98-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71639-98-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,6,3 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 71639-98:
(7*7)+(6*1)+(5*6)+(4*3)+(3*9)+(2*9)+(1*8)=150
150 % 10 = 0
So 71639-98-0 is a valid CAS Registry Number.

Palladium-Catalyzed Esterification of Carboxylic Acids with Aryl Iodides
Kitano, Hiroyuki,Ito, Hideto,Itami, Kenichiro
, p. 2428 - 2432 (2018)
The first palladium-catalyzed esterification of carboxylic acids with aryl iodides is described. A palladium-based catalytic system consisting of IBnF (1,3-bis((pentafluorophenyl)methyl)imidazole-2-ylidene) ligand was found to significantly acc
