Check Digit Verification of cas no

The CAS Registry Mumber 121758-19-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,7,5 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 121758-19:
(8*1)+(7*2)+(6*1)+(5*7)+(4*5)+(3*8)+(2*1)+(1*9)=118
118 % 10 = 8
So 121758-19-8 is a valid CAS Registry Number.

Palladium-Catalyzed Modular Synthesis of Substituted Piperazines and Related Nitrogen Heterocycles

Montgomery, Thomas D.,Rawal, Viresh H.

supporting information, p. 740 - 743 (2016/03/01)

We report here a novel method for the modular synthesis of highly substituted piperazines and related bis-nitrogen heterocycles via a palladium-catalyzed cyclization reaction. The process couples two of the carbons of a propargyl unit with various diamine components to provide nitrogen heterocycles in generally good to excellent yields and high regio- and stereochemical control. (Chemical Equation Presented).

Investigation of macrocyclisation routes to 1,4,7-triazacyclononanes: Efficient syntheses from 1,2-ditosylamides

Stones, Graham,Tripoli, Regis,McDavid, Colin L.,Roux-Duplgtre, Kewin,Kennedy, Alan R.,Sherrington, David C.,Gibson, Colin L.

, p. 374 - 384 (2008/10/09)

Two routes to the synthesis of a cyclohexyl-fused 1,4,7-triazacyclononane involving macrocyclisations of tosamides have been investigated. In the first approach, using a classic Richman-Atkins-type cyclisation of a cyclohexyl-substituted 1,4,7-tritosamide
