Calculate Digit Verification of CAS Registry Number 118307-64:
(8*1)+(7*1)+(6*8)+(5*3)+(4*0)+(3*7)+(2*6)+(1*4)=115
115 % 10 = 5

Duocarmycins, potent antitumor antibiotics produced by Streptomyces sp. structures and chemistry

Yasuzawa,Murol,Ichimura,Takahashi,Ogawa,Takahashi,Sano,Saitoh

, p. 378 - 391 (1995)

Seven novel potent antitumor antibiotics, duocarmycins A (1), C1 (2), C2 (3), D (4), B1 (5), B2 (6) and SA (7), were isolated from three independently collected Streptomyces sp. The complete structures, including absolute stereochemistry, were determined by spectral and chemical studies of those duocarmycins and several derivatives. Duocarmycins A (1) and SA (7) possess a 1,2,7,7a-tetrahydrocycloprop[1,2-c]indol-4-one subunit, a common pharmacophore with that of CC-1065 (10) found from Streptomyces zelensis.
