Check Digit Verification of cas no
The CAS Registry Mumber 57110-29-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,1,1 and 0 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 57110-29:
(7*5)+(6*7)+(5*1)+(4*1)+(3*0)+(2*2)+(1*9)=99
99 % 10 = 9
So 57110-29-9 is a valid CAS Registry Number.

Use of an acetylenic sulfone as an alkene dipole equivalent in the synthesis of (±)-pumiliotoxin C
Back, Thomas G.,Nakajima, Katsumasa
, p. 989 - 992 (2007/10/03)
The cycloaddition of methyl cis-2-amino-trans-6-methylcyclohexanecarboxylate (3) with 1-p-(toluenesulfonyl)-1-pentyne (4) afforded the corresponding enaminone 2, that was in turn reduced to (±)-pumiliotoxin C (1). The acetylenic sulfone 4 thus functions as the synthetic equivalent of the alkene dipole 5 in this process.
Process for stereoisomerization of cis-3-methyl-Δ4 -tetrahydro-cis,cis-phthalic anhydride
-
, (2008/06/13)
A process is provided for isomerizing (1) cis-3-methyl-Δ4 -tetrahydro-cis,cis-phthalic anhydride into (2) trans-3-methyl-Δ4 -tetrahydro-cis,cis-phthalic anhydride, which is its stereoisomer, by heating the compound (1) preferably at a temperature of 100° to 250° C. in the presence of an alkali metal compound such as lithium hydroxide, sodium hydroxide or sodium acetate. A mixture of said compounds (1) and (2) in a ratio by weight of 7:3 to 2:8 obtained by the isomerization reaction is liquid at room temperature and can be used advantageously as a curing agent for epoxy resins.
