Check Digit Verification of cas no
The CAS Registry Mumber 764724-38-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,6,4,7,2 and 4 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 764724-38:
(8*7)+(7*6)+(6*4)+(5*7)+(4*2)+(3*4)+(2*3)+(1*8)=191
191 % 10 = 1
So 764724-38-1 is a valid CAS Registry Number.

Preparation method of (S)-4-chloro-2-aminobutyrate
-
Paragraph 0040; 0041, (2019/03/08)
The invention relates to the field of agricultural herbicides. In order to solve the problem of a relatively low yield, the invention provides a preparation method of (S)-4-chloro-2-aminobutyrate. Thetechnical scheme is as follows: the preparation method comprises the following steps: carrying out ring-opening alcoholysis on (S)-2-amino butyrolactone under catalysis of an acid to obtain corresponding S-homoserine ester; and then carrying out chlorination by a chlorination agent to obtain a target product, wherein the reaction formula is as shown in the description. The butyrolactone structurecan achieve synchronous ring opening and synchronous esterification in a system of alcohol under the catalysis of a strong acid, and chemical equilibrium is continuously promoted to move forward to obtain the (S)-4-chloro-2-aminobutyrate with a high yield.
