69202-21-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 69202-21-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,2,0 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 69202-21:
(7*6)+(6*9)+(5*2)+(4*0)+(3*2)+(2*2)+(1*1)=117
117 % 10 = 7
So 69202-21-7 is a valid CAS Registry Number.

Direct Carboxylation of Electron-Rich Heteroarenes Promoted by LiO-tBu with CsF and [18]Crown-6

Shigeno, Masanori,Hanasaka, Kazuya,Sasaki, Keita,Nozawa-Kumada, Kanako,Kondo, Yoshinori

supporting information, p. 3235 - 3239 (2019/02/13)

We herein demonstrate that the combination of LiO-tBu, CsF, and [18]crown-6 efficiently promotes the direct C?H carboxylation of electron-rich heteroarenes (benzothiophene, thiophene, benzofuran, and furan derivatives). A variety of functional groups, including methyl, methoxy, halo, cyano, amide, and keto moieties, are compatible with this system. The reaction proceeds via the formation of a tert-butyl carbonate species.
