5439-14-5 Usage
Purification Methods
Dissolve it in CHCl3, filter, evaporate, then recrystallise the residue from EtOH/Me2CO (needles) which can be washed with Et2O and dried. It can also be recrystallised from CHCl3/pet ether or CHCl3/hexane. The hydrochloride has m 295-295o (dec, from EtOH or MeOH/Et2O), the hydrobromide has m 299-300o(dec) (from MeOH/Et2O) and the picrate has m 224-226o(corr), m 219-220o from EtOH.

Check Digit Verification of cas no
The CAS Registry Mumber 5439-14-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,3 and 9 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5439-14:
(6*5)+(5*4)+(4*3)+(3*9)+(2*1)+(1*4)=95
95 % 10 = 5
So 5439-14-5 is a valid CAS Registry Number.
