Calculate Digit Verification of CAS Registry Number 127945-26:
(8*1)+(7*2)+(6*7)+(5*9)+(4*4)+(3*5)+(2*2)+(1*6)=150
150 % 10 = 0
So 127945-26-0 is a valid CAS Registry Number.

Antibiotics from Gliding Bacteria, XLII. Chemical Modification of Sorangicin A and Structure - Activity Relationship I: Carboxyl and Hydroxyl Group Derivatives

Jansen, Rolf,Schummer, Dietmar,Irschik, Herbert,Hoefle, Gerhard

, p. 975 - 988 (2007/10/02)

The synthesis of selectively protected sorangicin A derivatives and their application in the modification of the hydroxyl groups and the carboxyl group in sorangicin A (1) is described.Esters, amides, and sorangicins modified at the hydroxyl groups were prepared and their activities against Staphylococcus aureus, Escherichia coli, and their in vitro inhibition of RNA polymerase were examined.Although no sorangicin A derivatives with superior biological activity were observed, some derivatives completely retained their antibiotic activity or were slightly improved in their activity with certain strains.
