Check Digit Verification of cas no

The CAS Registry Mumber 1379659-98-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,9,6,5 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1379659-98:
(9*1)+(8*3)+(7*7)+(6*9)+(5*6)+(4*5)+(3*9)+(2*9)+(1*8)=239
239 % 10 = 9
So 1379659-98-9 is a valid CAS Registry Number.

Photooxygenation of a microbial arene oxidation product and regioselective Kornblum-DeLamare rearrangement: Total synthesis of zeylenols and zeylenones

Palframan, Matthew J.,Kociok-Koehn, Gabriele,Lewis, Simon E.

, p. 4766 - 4774 (2012/05/04)

We report the enantioselective total syntheses of zeylenol (+)-1, as well as its congeners (-)-7 and 16, and of 3-O-debenzoylzeylenone 28. To this end, a new variant of the Kornblum-DeLaMare rearrangement, which utilises neighbouring-group participation to impart regioselectivity, has been developed. The approach employs photooxygenation of building blocks derived from a microbial arene oxidation product. New light on a Korny rearrangement: Biooxidation of benzoic acid with R. eutrophus B9 gives a dearomatised diene diol acid that allows concise access to the zeylenol and zeylenone family of polyoxygenated cyclohexene natural products. The synthesis employs diene photooxygenation and a new regioselective variant of the Kornblum-DeLaMare endoperoxide fragmentation has been developed (see scheme).
