Manufacturing Process
A solution of a Grignard reagent, employing 1-propyne (8 grams) was
prepared. To this reagent there was added the 3,3 ethylenedioxy derivative (4
grams) of 6-α-methylandrost-4-ene-3,17-dione in tetrahydrofuran (100 ml),
and the mixture heated under reflux for 3 hours. After decomposition of the
complex with aqueous ammonium chloride, the product was isolated with
ether and treated with 90% acetic acid (50 ml) for 30 minutes at 100°C. The
product obtained by pouring the mixture into water and extracting with ether
was crystallized from aqueous methanol. 17β-Hydroxy-6α-methyl-17α-(prop-
1-ynyl)androst-4-en-3-one formed plates MP 99° to 102°C.

Check Digit Verification of cas no
The CAS Registry Mumber 79-64-1 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 7 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 79-64:
(4*7)+(3*9)+(2*6)+(1*4)=71
71 % 10 = 1
So 79-64-1 is a valid CAS Registry Number.

Beta-cyclodextrin forms a water-soluble complex or inclusion compound with steroid compounds having a molecular structure smaller than the interior cavity in the doughnut-shaped molecular structure of beta-cyclodextrin. The resulting inclusion compounds can be used for a variety of applications including aqueous topical ophthalmic preparations and topical dermatological ointments.
