Calculate Digit Verification of CAS Registry Number 1515605-87:
(9*1)+(8*5)+(7*1)+(6*5)+(5*6)+(4*0)+(3*5)+(2*8)+(1*7)=154
154 % 10 = 4
So 1515605-87-4 is a valid CAS Registry Number.

Total synthesis of sandramycin and its analogues via a multicomponent assemblage

Katayama, Katsushi,Nakagawa, Koji,Takeda, Hiroshi,Matsuda, Akira,Ichikawa, Satoshi

, p. 428 - 431 (2014/04/03)

The total synthesis of sandramycin has been accomplished by using a Staudinger/aza-Wittig/diastereoselective Ugi three-component reaction sequence as a key step to obtain a linear pentadepsipeptide. Subsequent [5 + 5] coupling of the penptapeptide, macrolactamization, and introduction of the quinaldin chromophores afforded sandramycin. Dihydroxy and diacetoxy analogues were also prepared, and the cytotoxic activity of these analogues against a range of human cancer cell lines was evaluated.
