4134-58-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4134-58-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,3 and 4 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4134-58:
(6*4)+(5*1)+(4*3)+(3*4)+(2*5)+(1*8)=71
71 % 10 = 1
So 4134-58-1 is a valid CAS Registry Number.

Preparation process of 17a-hydroxyprogesterone acetate

-

Paragraph 0031-0038; 0039-0046; 0047-0054, (2017/07/21)

The invention discloses a preparation process of 17a-hydroxyprogesterone acetate. According to the invention, high-purity 17a-hydroxyprogesterone acetate is obtained sequentially through an acylation reaction, a hydrolysis reaction, a neutralization reaction, centrifugation and refining. Therefore, a process procedure is shortened, raw material input is reduced, and cost is saved.

Further syntheses of cyproterone acetate

-

Page/Page column 16; 28; 30; 32, (2010/02/07)

The present invention relates to improved methods for synthesising cyproterone acetate (17α-Acetoxy-6-chloro-1α, 2α-methylene-4,6-pregnadiene-3,20-dione) from solasodine. The methods of the invention are shorter as those of the prior art and therefore more economic.

15β-Hydroxysteroids (part V). Steroids of the human perinatal period: The synthesis of 3β, 15β, 17α-trihydroxy-5-pregnen-20- one from 15β, 17α-dihydroxy-4-pregnen-3,20-dione

Joannou,Reeder

, p. 18 - 21 (2007/10/03)

A simple three-step synthetic method is reported on the conversion of Δ4-3-ketosteroids to the corresponding 3β- hydroxy-Δ5-steroid analogues. 17α-Hydroxy-4-pregnen-3,20-dione (10a) was used as a model to develop a method for the synthesis of 3β,17α-dihydroxy-5-pregnen-20-one (16). The major problem being the synthesis of 3,17α-diacetoxy-3,5-pregnadien-20-one (14) was solved by acetylating using a mixture of acetic anhydride and perchloric acid. The conversion of 15β,17α-dihydroxy-4-pregnen- 3,20-dione (8), product of Penicillium citrinum fermentation, to the desired 3β, 15β, 17α-trihydroxy-5-pregnen-20-one (1), is described using a modification of this method. Reaction of 8 with acetic anhydride and perchloric acid in ethyl acetate gave 3,15β,17α-triacetoxy-3,5-pregnadien-20-one (17) which on reduction with sodium borohydrice gave 5-pregnen-3β,15β,17α, 20(S + R)-tetrols (18a and 18b); however, reduction of 17 with a mixture of sodium borohydride and potassium bicarbonate gave after basic hydrolysis with metanolic sodium hydroxide the desired product 3β,15β,17α-trihydroxy-5-pregnen-20-one (1) in good yield (54%).
