Flammability and Explosibility
Nonflammable
Check Digit Verification of cas no
The CAS Registry Mumber 821-38-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,2 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 821-38:
(5*8)+(4*2)+(3*1)+(2*3)+(1*8)=65
65 % 10 = 5
So 821-38-5 is a valid CAS Registry Number.

Bioassay-guided fractionation of the extract of the rare deep-sea marine sponge Pleroma sp. afforded seven new linear acetylenes, yakushynols A-F (1-6) and neopetroformyne E (7). The structures of 1-7 were determined by a combination of the analysis of spectroscopic data and chemical derivatization. Compounds 1-6 are the first examples of the sponge-derived acetylenes of the size of duryne with oxidation at the sixth carbon from the terminus. Compounds 1-5 and 7 exhibited moderate cytotoxic activity. A biosynthetic route of neopetroformyne A was inferred from the structural transition among sponge-derived linear acetylenes.

Ozonolyses in pentane of the unsubstituted cycloolefins having eleven-, twelve-, fourteen- and sixteen-membered rings (1b-e) and of cyclohexadecen-8-one (12) gave the corresponding cis- (2b-e; cis-15a) and trans-ozonides (3b-e; trans-15a), whereas cyclodecene (1a) gave only the corresponding cis-ozonide (2a).Ozonolyses on polyethylene of the dimethyl-substituted cycloolefins bearing fourteen- and sixteen-membered rings (7b,c) also afforded cis- and trans-isomeric ozonides (8, 9), whereas from the twelve-membered ring (7a) only the corresponding cis-ozonide (8a) was formed. - Keywords: Ozonides; Cycloolefins
