Check Digit Verification of cas no

The CAS Registry Mumber 844638-86-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,4,6,3 and 8 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 844638-86:
(8*8)+(7*4)+(6*4)+(5*6)+(4*3)+(3*8)+(2*8)+(1*6)=204
204 % 10 = 4
So 844638-86-4 is a valid CAS Registry Number.

Diastereoselective synthesis of 2,5-disubstituted decahydroquinolines via ring-rearrangement metathesis and zirconium-mediated cyclization

Neidhoefer, Juergen,Blechert, Siegfried

, p. 3047 - 3054 (2004)

A diastereoselective approach to 2,5-substituted decahydroquinolines by zirconium-mediated cyclization of unsaturated α,α′- disubstituted piperidines II is described. The required piperidines could be obtained from secondary sulfonamides III via ruthenium-catalyzed ring-rearrangement metathesis (RRM) in high yields. Racemic trans-195A and 2-epi-trans-195A were synthesized in 8 steps starting with butyraldehyde and cyclohex-2-enol.
