Purification Methods
Triturate the solid with 90% aqueous MeOH, filter, wash with 90% aqueous MeOH and dry it in a vacuum. Recrystallise it from MeOH (needles or plates), but use warm MeOH and cool to crystallise; do not boil as it decomposes slowly. IR has max 1785 (C=O) cm-1 and NMR (CDCl3) usually shows two tert-butyl singlets for syn and anti isomers. Store it in a brown bottle (fridge). It evolves CO2 at room temperature (stoppered bottle can explode!), but can be stored over silica gel which may extend its useful life to more than a year. [Itoh et al. Org Synth 59 95 1980.]
Check Digit Verification of cas no
The CAS Registry Mumber 58632-95-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,6,3 and 2 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 58632-95:
(7*5)+(6*8)+(5*6)+(4*3)+(3*2)+(2*9)+(1*5)=154
154 % 10 = 4
So 58632-95-4 is a valid CAS Registry Number.
