Check Digit Verification of cas no

The CAS Registry Mumber 201289-57-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,2,8 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 201289-57:
(8*2)+(7*0)+(6*1)+(5*2)+(4*8)+(3*9)+(2*5)+(1*7)=108
108 % 10 = 8
So 201289-57-8 is a valid CAS Registry Number.

Total syntheses of macrocyclic marine alkaloids, haliclamines A and B: A convenient and expeditious assembly of 3-substituted pyridine derivatives with different alkyl chains to the bispyridinium macrocycle

Morimoto, Yoshiki,Yokoe, Chiho,Kurihara, Hajime,Kinoshita, Takamasa

, p. 12197 - 12214 (1998)

The total syntheses of haliclamines A (1) and B (2), macrocyclic marine alkaloids closely related to the key bisdihydropyridine intermediate 3 of the biogenetically unique manzamine family, have efficiently been achieved via stepwise controlled inter- and intramolecular N-alkylations of 3- alkylpyridine derivatives such as 40 and 41. The general synthetic methodology toward the bispyridinium macrocycle 44, a key biogenetic equivalent of the polycyclic marine alkaloids, has been proposed through the total syntheses.

Synthesis of extremely simplified compounds possessing the key pharmacophore units of taxol, phenylisoserine and oxetane moieties

Fuji, Kaoru,Watanabe, Yukari,Ohtsubo, Tadamune,Nuruzzaman, Mohammad,Hamajima, Yoshio,Kohno, Michiaki

, p. 1334 - 1337 (2007/10/03)

Straight chain compounds having a phenylisoserine unit and an oxetane ring at the α- and ω- position, respectively as extremely simplified analogues of taxol were prepared. None of these compounds showed promising tubulin inhibitory activity.

Total synthesis of haliclamine A, a macrocyclic marine alkaloid related to the key biogenetic intermediate of manzamines

Morimoto, Yoshiki,Yokoe, Chiho

, p. 8981 - 8984 (2007/10/03)

The first total synthesis of haliclamine A (1), a macrocyclic marine alkaloid closely related to the key bisdihydropyridine intermediate 3 of the biogenetically unique manzamine family, has been efficiently achieved via stepwise inter- and intramolecular N-alkylations of 3-alkylpyridine derivatives 26 and 28.
