Check Digit Verification of cas no

The CAS Registry Mumber 303755-59-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,3,7,5 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 303755-59:
(8*3)+(7*0)+(6*3)+(5*7)+(4*5)+(3*5)+(2*5)+(1*9)=131
131 % 10 = 1
So 303755-59-1 is a valid CAS Registry Number.

Palladium-catalyzed carbonylation of iminoquinones and aryl iodides to access arylp-amino benzoates

Wang, Siqi,Wu, Xiao-Feng,Yao, Lingyun,Ying, Jun

supporting information, p. 8246 - 8249 (2021/10/12)

A palladium-catalyzed carbonylation of iminoquinones and aryl iodides has been developed for the construction of arylp-amino benzoates. Using benzene-1,3,5-triyl triformate (TFBen) as the CO source, the reaction proceeded well to give various arylp-amino benzoates in good to excellent yields. Additionally, control experiments were conducted to gain more insights into the reaction mechanism.
