Check Digit Verification of cas no

The CAS Registry Mumber 389123-28-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,9,1,2 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 389123-28:
(8*3)+(7*8)+(6*9)+(5*1)+(4*2)+(3*3)+(2*2)+(1*8)=168
168 % 10 = 8
So 389123-28-8 is a valid CAS Registry Number.

Total syntheses of (+)-zampanolide and (+)-dactylolide exploiting a unified strategy

Smith III, Amos B.,Safonov, Igor G.,Corbett, R. Michael

, p. 11102 - 11113 (2007/10/03)

The first total syntheses of (+)-zampanolide (1) and (+)-dactylolide (2), members of a new class of tumor cell growth inhibitory macrolides, have been achieved. Key features of the unified synthetic scheme included the stereocontrolled construction of the cis-2,6-disubstituted tetrahydropyran via a modified Petasis-Ferrier rearrangement, a highly convergent assembly of the macrocyclic domain, and, in the case of zampanolide, a Curtius rearrangement/acylation tactic to install the N-acyl hemiaminal. The complete relative and absolute stereochemistries for both (+)-zampanolide and (+)-dactylolide were also assigned, albeit tentatively in the case of (+)-zampanolide (1).
