Check Digit Verification of cas no

The CAS Registry Mumber 97549-48-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,5,4 and 9 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 97549-48:
(7*9)+(6*7)+(5*5)+(4*4)+(3*9)+(2*4)+(1*8)=189
189 % 10 = 9
So 97549-48-9 is a valid CAS Registry Number.

Total syntheses of (±)-cherylline and (±)-latifine

Couture, Axel,Deniau, Eric,Lebrun, Stephane,Grandclaudon, Pierre

, p. 789 - 794 (2007/10/03)

A new total synthesis of the two phenolic alkaloids (±)-cherylline 1 and (±)-latifine-2 isolated from Crinum species is described. The two key steps in the elaboration of these natural products are an anionic variant of the Fries rearrangement which gives

Synthesis of Amaryllidaceae Alkaloids, (+/-)-Cherylline and (+/-)-Latifine

Katakawa, Jun'Ichi,Yoshimatsu, Hideaki,Yoshida, Morihiro,Zhang, Yong,Irie, Hiroshi,Yajima, Haruaki

, p. 3928 - 3932 (2007/10/02)

Synthesis of the alkaloids, (+/-)-cherylline (1) and (+/-)-latifine (2), was accomplished by application of an isocyanate cyclization reaction according to Tsuda's two step procedure for constructing 1,2,3,4-tetrahydroisoquinol-1-one and a regioselective

Structure and Synthesis of a Novel Alkaloid, Latifine, from Crinum latifolium

Kobayashi, Shigeru,Tokumoto, Toshihiro,Iguchi, Seiichiro,Kihara, Masaru,Imakura, Yasuhiro,Taira, Zenei

, p. 2444 - 2470 (2007/10/02)

A novel alkaloid, latifine, was isolated from leaves and bulbs of Crinum latifolium L. (Amaryllidaceae), and the structure (1) of the base was elucidated from spectral data, biogenetic considerations, X-ray analysis, and synthesis of its racemate.

Total Synthesis of (+/-)- and (+)-Latifine

Takano, Seicchi,Akiyama, Masashi,Ogasawara, Kunio

, p. 2447 - 2454 (2007/10/02)

Racemic latifine (+)-(1), a new representative of the rare phenolic Amaryllidaceae alkaloids, has been synthesized by employing the Claisen rearrangement of 4-benzyloxycinnamyl 2-methoxyphenyl ether (11) as a key step.Based on the racemic synthesis, (R)-(

THE TOTAL SYNTHESIS OF (+/-)-LATIFINE

Takano, Seiichi,Akiyama, Masashi,Ogasawara, Kunio

, p. 505 - 506 (2007/10/02)

Latifine, a novel phenolic isoquinoline base from Crinum latifolium L. (Amaryllidaceae), has been synthesized.
