Check Digit Verification of cas no

The CAS Registry Mumber 87121-05-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,1,2 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 87121-05:
(7*8)+(6*7)+(5*1)+(4*2)+(3*1)+(2*0)+(1*5)=119
119 % 10 = 9
So 87121-05-9 is a valid CAS Registry Number.

Total Synthesis of the Antitumor-Antitubercular 2,6′-Bijuglone Natural Product Diospyrin and Its 3,6′-Isomer

Pullella, Glenn A.,Vuong, Daniel,Lacey, Ernest,Piggott, Matthew J.

supporting information, p. 3623 - 3634 (2021/01/09)

The 2,6′-bijuglone natural product diospyrin and its unnatural 3,6′-isomer idospyrin have been synthesized in seven steps each from N,N-diethylsenecioamide in overall yields of 12% and 13%, respectively. The syntheses diverge from ramentaceone (7-methylju

3-Methyl 1,1-bis(trimethylsiloxy) 1,3-butadiene et 4-trimethylsilyl 3-methyl 2-butenoate de trimethylsilyle: preparations et reactions avec le benzaldehyde

Bellassoued, M.,Ennigrou, R.,Gaudemar, M.

, p. 19 - 25 (2007/10/02)

The regioselectivity of the reaction between benzaldehyde and the silylketene acetal prepared from trimethylsilylsenecioate is studied as a function of the catalyst used.CsF leads exclusively to the "branched" product whereas TiCl4 gives the required "lin

SYNTHETIC STUDIES ON NOGALAMYCIN CONGENERS ; SYNTHESES AND ANTITUMOR ACTIVITY OF VARIOUS NOGALAMYCIN CONGENERS

Matsuda, Fuyuhiko,Kawasaki, Motoji,Ohsaki, Masako,Yamada, Kaoru,Terashima, Shiro

, p. 5745 - 5760 (2007/10/02)

Various structural types of nogalamycin congeners and their partial structures, which had been previously synthesized in the course of our synthetic studies on the total syntheses or were originally produced by employing the explored synthetic scheme, were subjected to in vitro cytotoxicity and in vivo antitumor activity assay against P388 murine leukemia.These studies obviously disclosed novel aspects of the structure-activity relationships of nogalamycin congeners.

Halogenated Ketenes. 37. The Synthesis of Pyranones Utilizing the (4 + 2) Cycloaddition of Ketenes and Siloxy Dienes

Brady, William T.,Agho, Michael O.

, p. 501 - 506 (2007/10/02)

The reaction of diphenyl-, dichloro-, and chloroketenes with several siloxy dienes results in (4 + 2) and/or (2 + 2) cycloaddition products depending primarily on substitution in the diene.The (4 + 2) cycloaddition products are easily hydrolyzed to pyranones.These results are discussed in terms of a dipolar intermediate.
