Check Digit Verification of cas no

The CAS Registry Mumber 128013-65-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,0,1 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 128013-65:
(8*1)+(7*2)+(6*8)+(5*0)+(4*1)+(3*3)+(2*6)+(1*5)=100
100 % 10 = 0
So 128013-65-0 is a valid CAS Registry Number.

Preparation method of pregabalin intermediate ethyl 3-nitromethyl-5-methylhexanoate

-

Paragraph 0035; 0038; 0040; 0042; 0044-0046; 0048; 0050, (2019/01/08)

The invention discloses a preparation method of a pregabalin intermediate ethyl 3-nitromethyl-5-methylhexanoate. The method comprises the steps: reacting raw materials, namely ethyl 5-methyl-2-hexenoate as shown in a formula I and nitromethane in an appropriate organic solvent A at 20-150 DEG C under the action of a supported organic catalyst by taking nitromethane as a nucleophilic reagent to prepare ethyl 3-nitromethyl-5-methylhexanoate as shown in a formula II, wherein the organic solvent A is one selected from the followings: acetonitrile, methanol, ethyl acetate, dichloromethane, ethanol,toluene and 1,4-dioxane. Ethyl 3-nitromethyl-5-methylhexanoate is prepared by using the supported organic catalyst low in cost, easy to prepare and environment-friendly and is high in reaction yieldand product purity.

PROCESS FOR PREPARING PREGABALIN

-
