Check Digit Verification of cas no

The CAS Registry Mumber 1352998-04-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,2,9,9 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1352998-04:
(9*1)+(8*3)+(7*5)+(6*2)+(5*9)+(4*9)+(3*8)+(2*0)+(1*4)=189
189 % 10 = 9
So 1352998-04-9 is a valid CAS Registry Number.

Oxidation of acyclic alkenes and allyl and benzyl ethers with DIB/t-BuOOH/Mg(OAc)2

Sastraruji, Thanapat,Pyne, Stephen G.,Ung, Alison T.

, p. 598 - 602 (2012)

Oxidation of (11Z)-1′,2′-didehydrostemofoline with DIB/TBHP/Mg(OAc)2·4H2O resulted in oxidative cleavage of the C-11-C-12 double bond instead of the desired allylic oxidation of the 1-butenyl side chain. Stemofoline gave a similar result. The oxidation of more simple terminal alkenes was regioselective and gave vinyl ketones while allyl and benzyl ethers gave acrylate and benzoate esters, respectively. Allyl and benzyl ethers could be chemoselectively oxidized in the presence of a terminal alkene or benzyl group. Oxidation of an internal alkene was poorly regioselective, in contrast to the oxidation of 1-substituted cyclohexenes.
