Calculate Digit Verification of CAS Registry Number 155435-50:
(8*1)+(7*5)+(6*5)+(5*4)+(4*3)+(3*5)+(2*5)+(1*0)=130
130 % 10 = 0
So 155435-50-0 is a valid CAS Registry Number.

New antiviral antibiotics, kistamicins A and B. II. Structure determination

Naruse,Oka,Konishi,Oki

, p. 1812 - 1818 (1993)

The structures of antiviral antibiotics kistamicins A and B have been determined by a combination of chemical degradation and spectral analysis. They are commonly composed of D-tyrosine 3,5-dihydrophenylglycine a biphenyl ether bis-amino acid and a diphenyl substituted indole tris-amino acid forming a tricyclic ring structure. Kistamicin B possessed a phenethylamide at the amino terminal of kistamicin A. They are structurally related to the nuclei of the vancomycin group antibiotics particularly to antibiotic complestatin.
