Check Digit Verification of cas no

The CAS Registry Mumber 207691-11-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,7,6,9 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 207691-11:
(8*2)+(7*0)+(6*7)+(5*6)+(4*9)+(3*1)+(2*1)+(1*1)=130
130 % 10 = 0
So 207691-11-0 is a valid CAS Registry Number.

Transition-Metal-Free DMAP-Mediated Aromatic Esterification of Amides with Organoboronic Acids

Guo, Jiarui,Liu, Lantao,Wang, Tao,Wang, Yanqing,Xu, Kai,Zhang, Yuheng

supporting information, p. 3274 - 3277 (2021/06/26)

A new, transition-metal-free, effective method for aromatic esterification of amides with organoboronic acids has been developed. A wide range of benzoate derivatives were obtained with yields ranging from moderate to good. The catalytic reaction shows a broad substrate scope and excellent functional group tolerance. Conceptually, DMAP mediates the reaction and is crucial for this transformation.

N-heterocyclic carbene-catalyzed aerobic oxidative direct esterification of aldehydes with organoboronic acids

Meng, Jing-Jing,Gao, Min,Wei, Yu-Ping,Zhang, Wen-Qin

experimental part, p. 872 - 875 (2012/07/03)

A simple procedure affording benzoates through a NHC-catalyzed aerobic oxidative esterification of aldehydes with organoboronic acids has been disclosed. This process allows access to a wide variety of aromatic esters in good to excellent yields under simple, efficient, and sustainable reaction conditions (see scheme).
