864447-25-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 864447-25-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,4,4,4 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 864447-25:
(8*8)+(7*6)+(6*4)+(5*4)+(4*4)+(3*7)+(2*2)+(1*5)=196
196 % 10 = 6
So 864447-25-6 is a valid CAS Registry Number.

Synthesis and antibacterial activity of alkyl derivatives of the glycopeptide antibiotic A40926 and their amides

Maffioli, Sonia I.,Ciabatti, Romeo,Romano, Gabriella,Marzorati, Ettore,Preobrazhenskaya, Maria,Pavlov, Andrej

, p. 3801 - 3805 (2008/12/20)

New derivatives of the glycopeptide antibiotic A40926 were synthesized and evaluated for antimicrobial activity against VRE. Deacylated A40926 was obtained by microbial transformation of the parent antibiotic with the use of Actinoplanes teichomyceticus ATCC 31121. Regioselective synthesis of alkylated derivatives of Deacyl A40926 was carried out using lipophilic aliphatic and aromatic halides or aldehydes. Further modification of the two carboxylic acids was performed to increase antibiotic activity. Poor antimicrobial activity was observed for the derivatives obtained by lipophilic mono- or dialkylation of the amino groups present on the molecule, while simultaneous condensation of both carboxylic groups, in hydrophobic derivatives, with dibasic amines led to a strong increase in antibiotic activity.
