387-59-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 387-59-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,8 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 387-59:
(5*3)+(4*8)+(3*7)+(2*5)+(1*9)=87
87 % 10 = 7
So 387-59-7 is a valid CAS Registry Number.

Process for preparing 3-enol ethers of 11β-hydroxy-Δ4 -pregnene-3-ones and derivatives thereof
-
, (2008/06/13)
3-enol ethers of 11β-hydroxy-Δ4 -pregnene-3-ones are prepared by reacting triethylorthoacetate with an 11β-hydroxy-Δ4 -pregnene-3-one in a solvent which is at least 40% by weight or more ethanol and 60% by weight or less of a compatible oxygenated hydrocarbon liquid in the presence of an acid catalyst. This reaction forms a basis of a process for forming 6-halo-derivatives, particularly 6-chloro-Δ1,4,6 -pregnatrien -11β,17α,21-triol-3,20-dione.
