The CAS Registry Mumber 161906-44-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,9,0 and 6 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 161906-44:
(8*1)+(7*6)+(6*1)+(5*9)+(4*0)+(3*6)+(2*4)+(1*4)=131
131 % 10 = 1
So 161906-44-1 is a valid CAS Registry Number.

Total Synthesis of Homochiral Kadsurin Having the Natural Configuration

Ohshima, Toshihiro,Tanaka, Masahide,Mitsuhashi, Hiroshi,Maruno, Masao,Wakamatsu, Takeshi

, p. 139 - 146 (1995)

The total synthesis of kadsurin was achieved in a stereoselective manner.The stereoselective hydrogenation of the homochiral enone (12), obtained from the known tetracyclic lactone (7), afforded known ketone (13), the conversion of which into kadsurin has

THE FIRST TOTAL SYNTHESIS OF γ-SCHIZANDRIN AND GOMISIN N HAVING NATURAL CONFIGURATIONS

Tanaka, Masahide,Ohshima, Toshihiro,Mitsuhashi, Hiroshi,Maruno, Masao,Wakamatsu, Takeshi

, p. 739 - 742 (2007/10/02)

The total syntheses of γ-schizandrin and gomisin N were achieved in a stereoselective manner.The success of these synthesis heavily depends on the stereoselective reduction of tetracyclic lactones with magnesium in methanol.
