5422-69-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5422-69-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,2 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5422-69:
(6*5)+(5*4)+(4*2)+(3*2)+(2*6)+(1*9)=85
85 % 10 = 5
So 5422-69-5 is a valid CAS Registry Number.

PROCESS FOR MAKING ESTERS OF 2-ACETOXYALKANOIC ACIDS USING A 3,6-DIALKYL-1,4-DIOXANE-2,5-DIONE OR POLY-(ALPHA-HYDROXYALKANOIC ACID) AS A STARTING MATERIAL

-

Page/Page column 10; 11, (2015/09/28)

2-Acetoxyalkanoic acid esters are made in a reaction of a 3,6-dialkyl-1,4-dioxane-2,5-dione or a poly(α-hydroxyalkanoic acid), an acetate ester and an alcohol or phenol in the presence of a transesterification catalyst. Unlike previous methods for making 2-acetoxyalkanoic acid esters, this process proceeds in high yield and high selectivity to the desired product.

PROCESS FOR MAKING ESTERS OF 2-ACETOXYALKANOIC ACIDS USING AN ALPHA-HYDROXYALKANOIC ACID ESTER AND AN ACETATE ESTER AS STARTING MATERIALS

-

Page/Page column 9; 10, (2015/09/23)

2-Acetoxyalkanoic acid esters are made in a reaction of an α-hydroxyalkanoic acid ester and an acetate ester in the presence of a transesterification catalyst. Unlike previous methods for making 2-acetoxyalkanoic acid esters, this process proceeds in high yield and high selectivity to the desired product.

LACTATE PRODUCTION PROCESS

-

Page/Page column 23, (2014/04/04)

A process for producing a compound of formula (I) is provided. The process comprises reacting a mixture comprising a compound of formula (IIA) and a compound of formula (IIB) with an alkyl alcohol in the presence of a Candida antarctica lipase B enzyme to produce a product comprising the compound of formula (I) and the compound of formula (IIB); wherein R1 is C1 to C6 alkyl; and wherein R2 is H or C1 to C12 alkyl. Also provided are processes for the production of R-lactic acid, oligomeric R-lactic acid, R,R-lactide, poly-R-lactic acid, alkyl S-lactate, S-lactic acid, oligomeric S-lactic acid, S,S-lactide, poly S-lactic acid and stereocomplex polylactic acid.
