Purification Methods
Extract a solution of the aldehyde in *C6H6 with 20% aqueous sodium bisulfite, and the bisulfite adduct in the aqueous solution is decomposed by acidifying and heating whereby the aldehyde separates. It is collected, washed with H2O, dried in a vacuum. It is recrystallised from EtOH (m 140-141o) and then from Et2O (m 143-144o). [Gray & Bonner J Am Chem Soc 70 1249 1948, Angyal et al.

Check Digit Verification of cas no
The CAS Registry Mumber 531-99-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,3 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 531-99:
(5*5)+(4*3)+(3*1)+(2*9)+(1*9)=67
67 % 10 = 7
So 531-99-7 is a valid CAS Registry Number.
