Check Digit Verification of cas no

The CAS Registry Mumber 152171-09-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,1,7 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 152171-09:
(8*1)+(7*5)+(6*2)+(5*1)+(4*7)+(3*1)+(2*0)+(1*9)=100
100 % 10 = 0
So 152171-09-0 is a valid CAS Registry Number.

Asymmetric Organocatalytic Synthesis of Bisindoles – Scope and Derivatizations

Retich, Christina,Br?se, Stefan

, p. 60 - 77 (2018/01/17)

Starting from 3-vinylindoles and glyoxolate imines, we created a library of diverse 4,6-bis(1H-indole-3-yl)piperidine 2-carboxylates by using 10 mol-% of a chiral phosphoric acid. Utilising electron-withdrawing groups on the starting material during the r

Gold(I)-catalyzed dearomative rautenstrauch rearrangement: Enantioselective access to cyclopenta[ b ]indoles

Zi, Weiwei,Wu, Hongmiao,Toste, F. Dean

supporting information, p. 3225 - 3228 (2015/03/30)

A highly enantioselective dearomative Rautenstrauch rearrangement catalyzed by cationic (S)-DTBM-Segphosgold(I) is reported. This reaction provides a straightforward method to prepare enantioenriched cyclopenta[b]indoles. These studies show vast differenc
