1808-42-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1808-42-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,0 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1808-42:
(6*1)+(5*8)+(4*0)+(3*8)+(2*4)+(1*2)=80
80 % 10 = 0
So 1808-42-0 is a valid CAS Registry Number.

Cycloforskamide, a cytotoxic macrocyclic peptide from the sea slug Pleurobranchus forskalii

Tan, Karen Co,Wakimoto, Toshiyuki,Takada, Kentaro,Ohtsuki, Takashi,Uchiyama, Nahoko,Goda, Yukihiro,Abe, Ikuro

, p. 1388 - 1391 (2013/08/23)

A macrocylic dodecapeptide, cycloforskamide, was isolated from the sea slug Pleurobranchus forskalii, collected off Ishigaki Island, Japan. Its planar structure was deduced by extensive NMR analyses and was further confirmed by MS/MS fragmentation analyses. Finally, the absolute configuration was determined by total hydrolysis and chiral-phase gas chromatographic analysis. This novel dodecapeptide contains three d-amino acids and three thiazoline heterocycles and exhibits cytotoxicity against murine leukemia P388 cells, with an IC 50 of 5.8 μM.

Calyxamides A and B, cytotoxic cyclic peptides from the marine sponge Discodermia calyx

Kimura, Miki,Wakimoto, Toshiyuki,Egami, Yoko,Tan, Karen Co,Ise, Yuji,Abe, Ikuro

experimental part, p. 290 - 294 (2012/05/05)

Cyclic peptides containing 5-hydroxytryptophan and thiazole moieties were isolated from the marine sponge Discodermia calyx collected near Shikine-jima Island, Japan. The structures of calyxamides A (1) and B (2), including the absolute configurations of all amino acids, were elucidated by spectroscopic analyses and degradation experiments. The structures are similar to keramamides F and G, previously isolated from Theonella sp. The analysis of the 16S rDNA sequences obtained from the metagenomic DNA of D. calyx revealed the presence of Candidatus Entotheonella sp., an unculturable δ-proteobacterium inhabiting the Theonella genus and implicated in the biosynthesis of bioactive peptides.
