Purification Methods

Recrystallise 5-pregnane several times from Me2CO. The melting point is lowered (e.g. to 50-71o) if it is contaminated with the 5-isomer. [Butenandt et al. Chem Ber 6 4 2529 1931, Steiger & Reichstein Helv Chim Acta 21 161 1938, Beilstein 5 III 1120, 1121, 1125.]

The CAS Registry Mumber 641-85-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 641-85:
(5*6)+(4*4)+(3*1)+(2*8)+(1*5)=70
70 % 10 = 0
So 641-85-0 is a valid CAS Registry Number.
