Check Digit Verification of cas no

The CAS Registry Mumber 1027086-70-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,0,8 and 6 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1027086-70:
(9*1)+(8*0)+(7*2)+(6*7)+(5*0)+(4*8)+(3*6)+(2*7)+(1*0)=129
129 % 10 = 9
So 1027086-70-9 is a valid CAS Registry Number.

Coupling of alkenes and alkynes: Synthesis of the C1-C11 and C18-C28 fragments of miyakolide

Trost, Barry M.,Ashfeld, Brandon L.

supporting information; experimental part, p. 1893 - 1896 (2009/04/10)

A transition metal-mediated, atom-economical approach toward the crucial A and D rings of miyakolide is described. A Pd-catalyzed alkyne-alkyne coupling/6-endo-dig cyclization is employed to assemble the A ring fragment. The key D ring pyran is constructed utilizing an Ru-catalyzed alkene-alkyne coupling followed by a Pd-catalyzed allylic alkylation to establish the all-cis stereochemistry.
