Check Digit Verification of cas no

The CAS Registry Mumber 201025-02-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,0,2 and 5 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 201025-02:
(8*2)+(7*0)+(6*1)+(5*0)+(4*2)+(3*5)+(2*0)+(1*2)=47
47 % 10 = 7
So 201025-02-7 is a valid CAS Registry Number.

Enantiospecific approach to a quinane skeleton related to pentalenolactones

Pellegrinet, Silvina C.,Spanevello, Rolando A.

, p. 8623 - 8626 (1997)

A novel and general approach has been delineated for the enantiomerically pure synthesis of the angularly fused tricyclic system of the pentalenolactone family of compounds. D-Glucose is used as starting material and a diasteroselective Diels-Alder reaction sets the elements for the ring junctions.

Enantiospecific approach toward pentalenolactone

Testero, Sebastian A.,Spanevello, Rolando A.

, p. 3793 - 3796 (2007/10/03)

The enantiospecific assembly of the pentalenolactones' carbon skeleton was achieved in 17 steps and 16% overall yield from methyl α-D- glucopyranoside. The synthetic strategy relies on two highly efficient key steps: an exo-diastereoselective Diels Alder
