19360-15-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19360-15-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,3,6 and 0 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 19360-15:
(7*1)+(6*9)+(5*3)+(4*6)+(3*0)+(2*1)+(1*5)=107
107 % 10 = 7
So 19360-15-7 is a valid CAS Registry Number.

18-Substituted Steroids. Part 13. Improved Preparation of the Metabolites of Aldosterone Reduced in Ring A

Kirk, David N.,Rajagopalan, Maruthiandan S.

, p. 1343 - 1346 (2007/10/02)

Protection of the side-chain of aldosterone as the 21-t-butyldimethylsilyl (TBDMS) ether was also found to mask the 20-oxo function, by effectively locking the tautomeric structure of aldosterone into its 11,18:18,20-diepoxy form.Catalytic hydrogenation of aldosterone 21-TBDMS ether gave the 5α- or the 5β-dihydro derivative depending on the choice of solvent.Subsequent reduction of the carbonyl group at C-3, with either 'K-selectride' to form the 3-axial alcohol or lithium tri-t-butoxyaluminium hydride to form the 3-equatorial alcohol, was found to proceed without attack on the side-chain, to give convenient routes to the four isomeric tetrahydroaldosterones.

Catalytic hydrogenations of several 18-oxygenated 3-keto- 4 -steroids.
