Check Digit Verification of cas no
The CAS Registry Mumber 18933-33-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,3 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 18933-33:
(7*1)+(6*8)+(5*9)+(4*3)+(3*3)+(2*3)+(1*3)=130
130 % 10 = 0
So 18933-33-0 is a valid CAS Registry Number.

Preparation method of levocarnitine
-
Paragraph 0030; 0031; 0032; 0033, (2017/08/29)
The invention provides a preparation method of levocarnitine. The preparation method comprises the following steps: taking epoxy chloropropane as a starting material, then carrying out amination, cyaniding and carrying out ester exchange under the action of lipase CALB to obtain corresponding chiral ester, then carrying out alkaline hydrolysis and acidification, and then removing chlorine ions under the action of strongly alkaline resin, so that the levocarnitine finished product is obtained. In the invention, acid resin is used in an ester exchange process, and recemization can be realized, so that yield and optical purity of the levocarnitine are improved.

Page/Page column 22, (2009/09/26)
According to the present invention, by using 4-halogeno-3-hydroxybutanamide as a substrate in quaternary amination reaction with trialkylamine which is an important step in betaine (such as carnitine) preparation processes, it becomes possible to reduce the production of crotonic acid derivatives (the major by-product) greatly compared to conventional processes. Consequently, it becomes possible to prepare a betaine, such as carnitine, at a high yield. The present invention also relates to a process for preparing a betaine represented by formula (1) below, comprising a step of quaternary aminating an amide represented by formula (2) below: wherein A1, A2 and A3 individually represent a C1-C20 hydrocarbon group which may have a substituent(s); and X1 is a halogen atom.
