Check Digit Verification of cas no

The CAS Registry Mumber 1059153-44-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,9,1,5 and 3 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1059153-44:
(9*1)+(8*0)+(7*5)+(6*9)+(5*1)+(4*5)+(3*3)+(2*4)+(1*4)=144
144 % 10 = 4
So 1059153-44-4 is a valid CAS Registry Number.

Stereocontrolled total synthesis of (-)-gleenol using Claisen rearrangement of sterically congested dihydropyran

Nakazaki, Atsuo,Era, Tomohiro,Kobayashi, Susumu

, p. 770 - 771 (2008/12/21)

A stereocontrolled total synthesis of enantiomerically pure (-)-gleenol using an improved substrate to construct the spiro[4.5]decane through Claisen rearrangement has been achieved. The most striking feature of this synthesis is that the rearrangement of sterically congested dihydropyran, bearing all requisite substituants with proper stereochemistry, afforded the fully functionalized spiro[4.5]decane in a single step.
