Check Digit Verification of cas no

The CAS Registry Mumber 51644-27-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,6,4 and 4 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 51644-27:
(7*5)+(6*1)+(5*6)+(4*4)+(3*4)+(2*2)+(1*7)=110
110 % 10 = 0
So 51644-27-0 is a valid CAS Registry Number.

Synthesis of 1,4 bis(3' bromopropionyl) piperazine 2,3 14C via piperazine 2,3 14C

Kagemoto,Kishi,Minaki,Nakamura

, p. 489 - 496 (1973)

A simple procedure to synthesize 1,4 bis (3' bromopropionyl) piperazine 2,3 14C, pipobroman 14C(I 14C), via piperazine 2,3 14C (V 14C) is described. The condensation of 1,2 bis (benzylamino)ethane(II) with ethylene dibromide 1,2 14C gave 1,4 dibenzylpiperazine 2,3 14C(III 14C) in 34% yield. III 14C was catalytically reduced in glacial acetic acid on Pd C to afford piperazine 2,3 14C diacetate(IV 14C) in 90% yield, followed by the conversion in aqueous solution to free V 14C which was in turn subjected to a Schotten Baumann reaction with 3 bromopropionyl chloride to give I 14C in 69% yield.
