63968-26-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 63968-26-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,9,6 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 63968-26:
(7*6)+(6*3)+(5*9)+(4*6)+(3*8)+(2*2)+(1*6)=163
163 % 10 = 3
So 63968-26-3 is a valid CAS Registry Number.

Non-metal Lewis acid-catalyzed cross-Claisen condensation for β-keto esters

Han, Zhengyu,Huang, Hai,Meng, Fuliang,Yang, Zhenkun,Zhang, Tianyu,Zhou, Dapeng

supporting information, p. 9163 - 9166 (2021/11/16)

In this work, we disclose a new catalytic and highly chemoselective cross-Claisen condensation of esters. In the presence of TBSNTf2 as a non-metal Lewis acid, various esters can undergo cross-Claisen condensation to form β-keto esters which are important building blocks. Compared with the traditional Claisen condensation, this process, employing silyl ketene acetals (SKAs) as carbonic nucleophiles to achieve cross-Claisen condensation, requires mild conditions and has good tolerance of functional groups.
