Check Digit Verification of cas no

The CAS Registry Mumber 1268720-32-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,7,2 and 0 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1268720-32:
(9*1)+(8*2)+(7*6)+(6*8)+(5*7)+(4*2)+(3*0)+(2*3)+(1*2)=166
166 % 10 = 6
So 1268720-32-6 is a valid CAS Registry Number.

Total synthesis and bioactivities of two proposed structures of maresin

Sasaki, Kenji,Urabe, Daisuke,Arai, Hiroyuki,Arita, Makoto,Inoue, Masayuki

, p. 534 - 543 (2011/10/12)

Maresin is a potent anti-inflammatory lipid mediator derived from docosahexaenoic acid (DHA). A highly convergent total synthesis of two proposed structures of C7-epimeric maresins from the four known fragments was achieved in 17 steps. The three key coupling reactions were the BF3-mediated alkyne attack on the epoxide, chiral titanium complex-promoted enantioselective alkyne addition to the aldehyde, and a Julia-Kocienski olefination. The two synthesized diastereomers were found to be comparably active in blocking neutrophil infiltration in the acute peritonitis model. Copyright
