Check Digit Verification of cas no

The CAS Registry Mumber 205496-89-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,4,9 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 205496-89:
(8*2)+(7*0)+(6*5)+(5*4)+(4*9)+(3*6)+(2*8)+(1*9)=145
145 % 10 = 5
So 205496-89-5 is a valid CAS Registry Number.

A short asymmetric synthesis of (-)-neonepetalactone

Enders, Dieter,Kaiser, Anja

, p. 631 - 635 (1997)

(4S.,4aR)-Neonepetalactone (6) was synthesized in high diastereomeric and enantiomeric purity (de, ee ≥ 96 %) in a four step procedure. Key step of the total synthesis is the Michael addition of metalated propanal SAMP-hydrazone ((S)-1) to 2-cyclopentenecarboxylate (2).
