49637-59-4 Usage
Purification Methods
Distil it in a vacuum, percolate it through a column of alumina, then pass it through a packed column maintained at 150o to remove residual traces of volatile materials in a countercurrent stream of N2 under reduced pressure [Dobry & Keller J Phys Chem 61 1448 1957]. [Beilstein 16 III 884.]
Check Digit Verification of cas no
The CAS Registry Mumber 49637-59-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,6,3 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 49637-59:
(7*4)+(6*9)+(5*6)+(4*3)+(3*7)+(2*5)+(1*9)=164
164 % 10 = 4
So 49637-59-4 is a valid CAS Registry Number.
