Check Digit Verification of cas no

The CAS Registry Mumber 212189-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,2,1,8 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 212189-50:
(8*2)+(7*1)+(6*2)+(5*1)+(4*8)+(3*9)+(2*5)+(1*0)=109
109 % 10 = 9
So 212189-50-9 is a valid CAS Registry Number.

A photoredox-neutral Smiles rearrangement of 2-aryloxybenzoic acids

Gonzalez-Gomez, Jose C.,Ramirez, Nieves P.,Lana-Villarreal, Teresa,Bonete, Pedro

supporting information, p. 9680 - 9684 (2017/11/30)

We report on the use of visible light photoredox catalysis for the radical Smiles rearrangement of 2-aryloxybenzoic acids to obtain aryl salicylates. The method is free of noble metals and operationally simple and the reaction can be run under mild batch or flow conditions. Being a redox neutral process, no stoichiometric oxidants or reductants are needed.
