tert-?Butyl 4-?(4-?Amino-?6,?7-?dimethoxyquinazolin-?2-?yl)?piperazine-?1-?carboxylate is an impurity in the synthesis of Terazosin (T105000), an α-1-adrenergicblocker related to prazosin.
Check Digit Verification of cas no
The CAS Registry Mumber 1260939-66-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,0,9,3 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1260939-66:
(9*1)+(8*2)+(7*6)+(6*0)+(5*9)+(4*3)+(3*9)+(2*6)+(1*6)=169
169 % 10 = 9
So 1260939-66-9 is a valid CAS Registry Number.

Parallel synthesis of N-arylpiperazines using polymer-assisted reactions
Duncton, Matthew A. J.,Roffey, Jonathan R. A.,Hamlyn, Richard J.,Adams, David R.
, p. 2549 - 2552 (2006)
A series of N-arylpiperazines were prepared in a parallel fashion using palladium-catalyzed cross-coupling, or nucleophilic aromatic displacement chemistries, and polymer-assisted sequestration and purification techniques as key steps.
