Check Digit Verification of cas no
The CAS Registry Mumber 21408-05-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,4,0 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 21408-05:
(7*2)+(6*1)+(5*4)+(4*0)+(3*8)+(2*0)+(1*5)=69
69 % 10 = 9
So 21408-05-9 is a valid CAS Registry Number.

gem-cyclodialkylation A facile synthetic route to N-substituted heterocycles
Hargis, Duane C.,Shubkin, Ronald L.
, p. 2991 - 2994 (2007/10/02)
N-alkylated and N-arylated pyrroles, pyrrolidines, and piperidines are synthesized in high yield by the reaction between cyclic ethers and primary amines over a heterogeneous titania catalyst.
