Check Digit Verification of cas no

The CAS Registry Mumber 20013-26-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,0,1 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 20013-26:
(7*2)+(6*0)+(5*0)+(4*1)+(3*3)+(2*2)+(1*6)=37
37 % 10 = 7
So 20013-26-7 is a valid CAS Registry Number.

Tri(pentaflurophenyl)borane-catalyzed reduction of cyclic imides with hydrosilanes: Synthesis of pyrrolidines

Ding, Guangni,Wu, Xiaoyu,Lu, Bin,Lu, Wenkui,Zhang, Zhaoguo,Xie, Xiaomin

, p. 1144 - 1150 (2018)

B(C6F5)3-catalyzed hydrosilylation of cyclic imides afforded an efficient synthetic method of pyrrolidines. In the presence of 5 mol% B(C6F5)3, various aromatic, aliphatic and polycyclic imides were smoothly reduced by PhSiH3 to generate the corresponding pyrrolidines in high yields. The reaction profiles monitored by 1H NMR spectroscopy disclosed the reduction process of cyclic imides and the effect of difference structure of the hydrosilanes on the hydrosilylation.
