Check Digit Verification of cas no

The CAS Registry Mumber 108543-16-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,5,4 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 108543-16:
(8*1)+(7*0)+(6*8)+(5*5)+(4*4)+(3*3)+(2*1)+(1*6)=114
114 % 10 = 4
So 108543-16-4 is a valid CAS Registry Number.

Methyl 9-(2-(2,5-Dihydro-5-pentylfuryl))-nonanoate in the Copper-catalyzed Decomposition Products of Methyl Linoleate Hydroperoxide and Some Other Products

Tokita, Masako,Morita, Makio

, p. 309 - 314 (2007/10/02)

The hydroperoxide of methyl linoleate containing 95 percent 13-hydroperoxide and 5 percent 9-hydroperoxide was decomposed in benzene with 10-4 M cupric naphthenate at 7580 deg C under degassed conditions.The decomposition products were fractionated by Sephadex LH-20 column chromatography with chloroform-hexane (2 : 1, V/V) and the fractions were purified by HPLC.In addition to the known products, three compounds were identified as methyl 9-(2-(2,5-dihydro-5-pentylfuryl))-nonanoate, Methyl 8-(2-furyl)-octanoate, and methyl 9(13)-hydroperoxy-12,13-(9,10)-epoxy-10(12)-octadecenoate as miner decomposition products by MS and IR spectrophotometry.
