891699-63-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 891699-63-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,1,6,9 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 891699-63:
(8*8)+(7*9)+(6*1)+(5*6)+(4*9)+(3*9)+(2*6)+(1*3)=241
241 % 10 = 1
So 891699-63-1 is a valid CAS Registry Number.

Synthesis and?receptor binding studies of?3-substituted piperazine derivatives
Bedürftig, Stephan,Wünsch, Bernhard
, p. 387 - 396 (2007/10/03)
In order to find novel receptor ligands various substituents were introduced into the side chain in position 3 of the piperazine 5. During nucleophilic substitution of the hydroxy group of 5 aziridinium ions were formed, resulting in rearranged 1,4-diazep
