Check Digit Verification of cas no

The CAS Registry Mumber 134076-55-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,0,7 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 134076-55:
(8*1)+(7*3)+(6*4)+(5*0)+(4*7)+(3*6)+(2*5)+(1*5)=114
114 % 10 = 4
So 134076-55-4 is a valid CAS Registry Number.

Concise total syntheses of palominol, dolabellatrienone, β-araneosene, and isoedunol via an enantioselective Diels-Alder macrobicyclization

Snyder, Scott A.,Corey

, p. 740 - 742 (2007/10/03)

Concise total syntheses of four members of the dolabellane family of diterpenoid natural products are reported. Key features of the developed route include the first demonstration of an enantioselective, intramolecular Type I Diels-Alder macrobicyclization, the first example of a stereoselective π-allyl Stille coupling reaction involving a farnesyl-derived intermediate, a powerful new reagent for the formation of dithianes with acid-sensitive molecules, and a unique and highly efficient ring-contraction sequence based on a modified Wolff photochemical rearrangement.
