Check Digit Verification of cas no

The CAS Registry Mumber 6859-99-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,5 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6859-99:
(6*6)+(5*8)+(4*5)+(3*9)+(2*9)+(1*9)=150
150 % 10 = 0
So 6859-99-0 is a valid CAS Registry Number.

Multi-chiral nitrogen-substituted piperidinol derivative and preparation method thereof

-

Paragraph 0017, (2021/10/11)

The invention belongs to the technical field of preparation of chiral piperidine alcohol compounds. The invention particularly relates to a multi-chiral nitrogen-substituted piperidinol derivative and a preparation method thereof. The 3 -hydroxypyridine serves as a starting raw material, and the corresponding substrate is obtained through catalytic hydrogenation reduction, amino protection, hydroxyl oxidation and Stork enamine - carbon alkylation to obtain the corresponding substrate. The process is simple, the reaction conditions are mild, and in particular, the ketone reducing liquid enzyme (KRED - 101) is selectively catalyzed, so that a chiral target product is obtained, and the yield is stable and the three wastes are few. The obtained piperidine heterocyclic derivative with the chiral center body has a plurality of drug activities and is suitable for industrial production.

Preparation method of (S)-1-tert-butyloxycarbonyl-3-hydroxypiperidine

-

, (2020/03/25)

The invention discloses a preparation method of (S)-1-tert-butyloxycarbonyl-3-hydroxypiperidine, and relates to the technical field of biological pharmacy. The preparation method comprises the following steps: 1, preparing 3-hydroxypyridine (2) as a raw material; 2, preparing racemic 3-hydroxypiperidine (3) from 3-hydroxypyridine (2); 3, preparing a derivative (2S, 3S)-N-(4-chlorphenyl)-2, 3-dihydroxy succinamic acid (4) from racemic 3-hydroxypiperidine (3) and D-tartaric acid; 4, carrying out resolution reaction on the derivative (2S, 3S)-N-(4-chlorphenyl)-2, 3-dihydroxy succinamic acid (4) prepared from D-tartaric acid to obtain a (S)-hydroxypiperidine salt (5); and 5, subjecting an obtained mixture to extraction, concentration and crystallization, to prepare a (S)-1-tert-butyloxycarbonyl-3-hydroxypiperidine salt (5). The preparation process has the advantages that the synthesis steps are reduced, the yield is increased, an adopted chiral resolving agent can be recycled, and the preparation process is suitable for industrial production.

Preparation method of (S)-3-hydroxypiperidine

-

Paragraph 0018-0020; 0023, (2018/06/15)

The invention discloses a preparation method of (S)-3-hydroxypiperidine. The preparation method comprises the steps of (1) carrying out catalytic hydrogenation on 3-hydroxypyridine to prepare 3-hydroxypiperidine; (2) splitting the 3-hydroxypiperidine for preparing the (S)-3-hydroxypiperidine, wherein catalytic hydrogenation is carried out under the co-catalysis of a ruthenium/silicon dioxide catalyst and a cocatalyst; the weight ratio of the ruthenium/silicon dioxide catalyst to the cocatalyst is 1:1 to 3:1; the total weight of the ruthenium/silicon dioxide catalyst and the cocatalyst is 5 to10 percent of the weight of the 3-hydroxypiperidine; and the cocatalyst is aluminum oxide. According to the method provided by the invention, the ruthenium/silicon dioxide catalyst and the aluminum oxide are adopted as a compound catalyst for catalytic hydrogenation, and the compound catalyst is relatively cheap but has the same better catalysis effect, and pollutes environment less so as to be suitable for industrial production.
