24775-76-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 24775-76-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,7,7 and 5 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 24775-76:
(7*2)+(6*4)+(5*7)+(4*7)+(3*5)+(2*7)+(1*6)=136
136 % 10 = 6
So 24775-76-6 is a valid CAS Registry Number.

Methods For Preparing Fentanyl And Fentanyl Intermediates

-

Paragraph 0042; 0043; 0044; 0045; 0046; 0047; 0048, (2013/11/05)

A method and an intermediate are provided for preparing fentanyl. Aniline and 1-phenylethyl-4-piperidone are reacted with a borane complex, in a lower C1-C4 alcoholic solvent, in the presence of an alkanoic acid. The reaction mixture is then treated with a hydrohalic acid to precipitate 4-anilino-N-phenethyl-4-piperidine (ANPP) as the bis-hydrohalide salt in high yield and purity. This ANPP salt may be directly treated with propionyl halide to produce fentanyl, or the ANPP salt may be converted to the free base of ANPP and similarly treated with propionyl halide to produce fentanyl.
