Calculate Digit Verification of CAS Registry Number 1319727-19:
(9*1)+(8*3)+(7*1)+(6*9)+(5*7)+(4*2)+(3*7)+(2*1)+(1*9)=169
169 % 10 = 9
So 1319727-19-9 is a valid CAS Registry Number.

Pyrroles and indolizidines from deprotonated α-(alkylideneamino) nitriles

Schaefer, Ines,Opatz, Till

experimental part, p. 1691 - 1704 (2011/07/29)

Their ready availability from simple starting materials in only two synthetic steps and their versatility as building blocks for the construction of highly substituted amines and N-heterocycles renders α-(alkylideneamino) nitriles useful synthetic intermediates. Herein, short syntheses of tri- and tetrasubstituted pyrroles including the northern half of the HMG-CoA reductase inhibitor atorvastatin as well as an access to 3-substituted indolizidines will be described.
