4859-16-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4859-16-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,5 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4859-16:
(6*4)+(5*8)+(4*5)+(3*9)+(2*1)+(1*6)=119
119 % 10 = 9
So 4859-16-9 is a valid CAS Registry Number.

STEREOREGULATION OF THE C(12b)H-C(2)H RELATIONSHIP IN THE PREPARATION OF 2-SUBSTITUTED 1,2,3,4,6,7,12,12b-OCTAHYDROINDOLOQUINOLIZINES

Lounasmaa, Mauri,Jokela, Reija

, p. 3975 - 3992 (2007/10/02)

Stereochemical control in the preparation of 2-substituted 1,2,3,4,6,7,12,12b-octahydroindoloquinolizines possessing at will the C(12b)H-C(2H) cis or trans configuration was achieved by catalytic reduction of the 2,3-dehydro analoques, which were either unsubstituted on the indole nitrogen or substituted with a BOC-group, respectively.The contribution of different conformations to the conformational equilibrium of the prepared compounds was estimated by 13C NMR spectral analysis.
