Calculate Digit Verification of CAS Registry Number 172427-05:
(8*1)+(7*7)+(6*2)+(5*4)+(4*2)+(3*7)+(2*0)+(1*5)=123
123 % 10 = 3
So 172427-05-3 is a valid CAS Registry Number.

Practical, Large-Scale Preparation of Benzoxepines and Coumarins through Rhodium(III)-Catalyzed C-H Activation/Annulation Reactions

Gulías, Moisés,Marcos-Atanes, Daniel,Mascare?as, José L.,Font, Marc

supporting information, p. 1669 - 1673 (2019/09/04)

Herein we disclose the assembly of benzoxepines and coumarins from 2-alkenylphenol precursors using [Cp*RhCl2]2 as the precatalyst and alkynes or carbon monoxide as reacting partners. The preparation of benzoxepines and coumarins can be scaled up to 33 mmol using low catalyst loadings.
