Purification Methods

Crystallise the acid from water. [Beilstein 3 IV 1975.]

Check Digit Verification of cas no

The CAS Registry Mumber 133-38-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 133-38:
(5*1)+(4*3)+(3*3)+(2*3)+(1*8)=40
40 % 10 = 0
So 133-38-0 is a valid CAS Registry Number.
