171076-49-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 171076-49-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,0,7 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 171076-49:
(8*1)+(7*7)+(6*1)+(5*0)+(4*7)+(3*6)+(2*4)+(1*9)=126
126 % 10 = 6
So 171076-49-6 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
