Check Digit Verification of cas no

The CAS Registry Mumber 250211-78-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,0,2,1 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 250211-78:
(8*2)+(7*5)+(6*0)+(5*2)+(4*1)+(3*1)+(2*7)+(1*8)=90
90 % 10 = 0
So 250211-78-0 is a valid CAS Registry Number.

Total syntheses and biological investigations of tamandarins A and B and tamandarin A analog

Liang,Richard,Portonovo,Joullie

, p. 4469 - 4474 (2007/10/03)

Tamandarins A (1) and B (2), two natural products similar in structure to didemnin B (3), were recently isolated from a Brazilian marine ascidian of the family Didemnidae. The cytotoxicity of 1 was reported to be somewhat more potent in vitro than that of 3 against various human cancer cell lines. The present account describes the first total syntheses of 1 and 2, and the syntheses of tamandarin A side chain analogues. The cytotoxicity data for these compounds show that the side chain modifications exhibit a parallel effect for both didemnins and tamandarins. This observation supports tamandarins' role as didemnins' mimic.
