Check Digit Verification of cas no
The CAS Registry Mumber 55989-13-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,9,8 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 55989-13:
(7*5)+(6*5)+(5*9)+(4*8)+(3*9)+(2*1)+(1*3)=174
174 % 10 = 4
So 55989-13-4 is a valid CAS Registry Number.

Paragraph 0006; 0009; 0011; 0015-0016, (2021/05/12)
The invention relates to a synthetic method of (S)-3-(4-chlorophenyl)-piperidine. The invention mainly aims to solve the technical problems of harsh reaction conditions, expensive catalysts, high cost, unsuitability for large-scale production and the like when optically pure (S)-3-(4-chlorophenyl)-piperidine is prepared by hydrogenating a pyridine ring and then utilizing chiral SFC. The synthesis method comprises the following four steps: (1) alpha-site alkylation of 4-chlorobenzyl cyanide; (2) reduction of 5-chloro-2-(4-chlorophenyl)valeronitrile; (3) cyclization of the 5-chloro-2-(4-chlorphenyl)amyl-1-amine to obtain (RS)-3-(4-chlorophenyl)-piperidine; and (4) chemical resolution of the (RS)-3-(4-chlorophenyl)-piperidine to obtain a final product. A target product with an optical purity reaching 98% or above is obtained through four-step reaction. The method is high in yield, low in cost, simple and convenient to operate and purify, good in economic benefits and more suitable for industrial production.
