Purification Methods
Purify it by fractional distillaton through a short Vigreux column (15mm, p 11). The 2,4-dinitrophenylhydrazone has m 212-213o (from EtOH). It is freely soluble in H2O but insoluble in Et2O. [McElvain & McMahon J Am Chem Soc 71 901 1949, Beilstein 21/6 V 246.]
Check Digit Verification of cas no
The CAS Registry Mumber 32161-06-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,1,6 and 1 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 32161-06:
(7*3)+(6*2)+(5*1)+(4*6)+(3*1)+(2*0)+(1*6)=71
71 % 10 = 1
So 32161-06-1 is a valid CAS Registry Number.
