Purification Methods
Purify the hydrobromide by boiling a saturated aqueous solution with charcoal, filtering and leaving the salt to crystallise. Store this dihydrate salt in a cool, stoppered flask in the dark place. The anhydrous salt is obtained by heating at 80o/4hours, and it is hygroscopic. The solubilities of the hydrobromide at 26o are 2.4% in EtOH, 0.6% in H2O, 0.3% in Et2O, 0.1% in Me2CO and 0.003% in *C6H6. [Dasgupta et al.

Check Digit Verification of cas no
The CAS Registry Mumber 40835-96-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,8,3 and 5 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 40835-96:
(7*4)+(6*0)+(5*8)+(4*3)+(3*5)+(2*9)+(1*6)=119
119 % 10 = 9
So 40835-96-9 is a valid CAS Registry Number.
