1931-65-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1931-65-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,3 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1931-65:
(6*1)+(5*9)+(4*3)+(3*1)+(2*6)+(1*5)=83
83 % 10 = 3
So 1931-65-3 is a valid CAS Registry Number.

Method of Preparing Aminoundecane Acid and 11-Aminoundecanoic Acid or Structural Isomer Thereof by Hydroformylation Reaction

-

Paragraph 0068; 0074-0095; 0119-0122, (2020/11/03)

The present invention relates to a method for preparing 11-aminoundecanoic acid or structural isomers thereof using a hydroformylation reaction. More particularly, the present invention is an eco-friendly method capable of preparing aminoundecanoic acid used as a monomer of polyamide and structural isomers thereof from an olefinic acid ester obtained through a metathesis reaction of oleic acid by means of hydroformylation, reductive amination reaction, and hydrolysis reaction, and capable of producing various polyamides having different physical properties according to a ratio of each isomer since the ratio of structural isomers can be adjusted according to a ligand.COPYRIGHT KIPO 2021
