Check Digit Verification of cas no

The CAS Registry Mumber 19139-76-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,1,3 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 19139-76:
(7*1)+(6*9)+(5*1)+(4*3)+(3*9)+(2*7)+(1*6)=125
125 % 10 = 5
So 19139-76-5 is a valid CAS Registry Number.

Convergent and stereoselective synthesis of (-)-zeaenol

Kumar, Rayala Naveen,Meshram

, p. 5669 - 5677 (2015)

Stereoselective synthesis of (-)-zeaenol has been accomplished from d-xylose as a chiral pool starting material. The key steps of this convergent synthetic strategy involves a Stille coupling, a Noyori reduction, a Julia-Kocienski olefination and a macrolactonization to obtain (-)-zeaenol. We have also explored a Sonogashira coupling along with a Trost protocol for the intramolecular hydrosilylation on the homopropargylic alcohol system as an alternative synthetic approach to this molecule.
