Check Digit Verification of cas no

The CAS Registry Mumber 54201-84-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,2,0 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 54201-84:
(7*5)+(6*4)+(5*2)+(4*0)+(3*1)+(2*8)+(1*4)=92
92 % 10 = 2
So 54201-84-2 is a valid CAS Registry Number.

Environmentally-friendly synthesis method of ulipristal acetate intermediate and ulipristal acetate

-

Paragraph 0027; 0042-0043, (2020/07/14)

The invention provides a method for environmentally-friendly synthesis of an ulipristal acetate intermediate and ulipristal acetate. According to the invention, a compound 2 is used as a starting rawmaterial, and reacts with acetylene in a solvent to form an alkynyl alcohol compound intermediate 3, a hydration reaction is performed with water under the catalysis of an ionic liquid and CO2 to obtain an intermediate 4, the intermediate 4 is subjected to carbonyl protection to obtain an intermediate 5, and the intermediate 5 is subjected to double bond epoxidation, a Grignard reaction, decarbonylation protection and acetylation to obtain the high-purity ulipristal acetate. The method is environment-friendly, convenient in steps, mild in conditions, low in cost, easy to amplify and suitable for industrial production, and the solvent can be recycled.

Cyclic utilization method of sterides epoxy isomer

-

Paragraph 0029-0033, (2018/06/04)

The invention provides a cyclic utilization method of sterides epoxy isomer. Biphenyl organic solvent is reacted with active metal lithium, sodium, and potassium, and others, and reduced to be conjugated double bond; under the alkali environment, the ketal protection radical group is not influenced, and 17- hydroxyl is also not influenced, thus the position of double bond is not changed and doublebonds are directly transformed to be raw material of the last step, and the raw materials are recycled. The method adopts one-step reduction, and solves the existing common technique of opening loopof epoxy bond firstly and then dewatering to be double bonds, and avoids that the ketal protection radical can be damaged by directly reducing epoxy bond to be double bonds by metal in the alkali environment; the epoxy isomer beta and a part of alpha isomer are directly reduced to be the raw material containing conjugated double bond in last step, thus a simple cycle is realized.

Preparation method of ulipristal acetate diketal

-

Page/Page column 9-11, (2019/01/11)

The invention discloses a preparation method of ulipristal acetate diketal. Dihydroxyprogesterone dehydrogenate 1 is used as the raw material to prepare an important intermediate of sterides, namely ulipristal acetate diketal 8; a reaction formula is shown in the attached figure. The preparation method has the advantages that the dihydroxyprogesterone dehydrogenate 1 is used as a starting raw material, seven steps are performed, and the ulipristal acetate diketal with weight total yield rate of 65% or above can be obtained; the reaction is simple, the selectivity is good, and the preparation method is suitable for industrialization production.
