Check Digit Verification of cas no

The CAS Registry Mumber 73831-66-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,8,3 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 73831-66:
(7*7)+(6*3)+(5*8)+(4*3)+(3*1)+(2*6)+(1*6)=140
140 % 10 = 0
So 73831-66-0 is a valid CAS Registry Number.

Direct and selective synthesis of 3-arylphthalides via nickel-catalyzed aryl addition/intramolecular esterification

Qiang, Qing,Liu, Feipeng,Rong, Zi-Qiang

, (2021)

Herein we report a nickel-catalyzed aryl addition/intramolecular esterification in a cascade fashion. Under the combination of commercially available nickel precursor and tridentate ligand, the one pot protocol offers a direct, simple and regioselective approach to access 3-aryl phthalide derivatives from two readily available substrates with good efficiency, broad scope as well as satisfactory functional group compatibility.
