Calculate Digit Verification of CAS Registry Number 17811-36:
(7*1)+(6*7)+(5*8)+(4*1)+(3*1)+(2*3)+(1*6)=108
108 % 10 = 8
So 17811-36-8 is a valid CAS Registry Number.

Incorporation of carbon dioxide into phthalides: Via ligand-free copper-catalyzed direct carboxylation of benzoxasiloles

Nguyen, Thanh V. Q.,Rodríguez-Santamaría, José A.,Yoo, Woo-Jin,Kobayashi, Shu

supporting information, p. 2501 - 2505 (2017/07/17)

The direct carboxylation of benzoxasiloles with carbon dioxide proceeded smoothly under mild conditions using copper iodide as a catalyst to afford phthalides after an acid work-up. Broad substrate scope and application of this methodology for the synthesis of natural products highlight the synthetic utility of this protocol.
