Check Digit Verification of cas no

The CAS Registry Mumber 68983-10-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,9,8 and 3 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 68983-10:
(7*6)+(6*8)+(5*9)+(4*8)+(3*3)+(2*1)+(1*0)=178
178 % 10 = 8
So 68983-10-8 is a valid CAS Registry Number.

Palladium-Catalyzed Esterification of Carboxylic Acids with Aryl Iodides

Kitano, Hiroyuki,Ito, Hideto,Itami, Kenichiro

supporting information, p. 2428 - 2432 (2018/04/27)

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

A New and Efficient Esterification Reaction via Mixed Anhydrides by the Promotion of a Catalytic Amount of Lewis Acid

Miyashita, Mitsutomo,Shiina, Isamu,Miyoshi, So,Mukaiyama, Teruaki

, p. 1516 - 1527 (2007/10/02)

In the presence of a catalytic amount of Lewis acid, various carboxylic esters or S-phenyl carbothioates are prepared in excellent yields by the respective reactions of equimolar amounts of silyl carboxylates and alkyl silyl ethers or phenyl silyl sulfides with 4-trifluoromethylbenzoic anhydride.
