173339-02-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 173339-02-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,3,3 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 173339-02:
(8*1)+(7*7)+(6*3)+(5*3)+(4*3)+(3*9)+(2*0)+(1*2)=131
131 % 10 = 1
So 173339-02-1 is a valid CAS Registry Number.

Synthesis and anti-tumor activity of new steroidal nuclear analogues of aragusterol A

Mitome, Hidemichi,Shinohara, Masakazu,Miyaoka, Hiroaki,Yamada, Yasuji

, p. 640 - 645 (2007/10/03)

3α,7α-Dihydroxy-5-epiaragusterol A (3) was synthesized from bile acid (cholic acid) as a new steroidal nuclear analogue of antitumor marine steroid aragusterol A. 7α-Hydroxyaragusterol A (4) was also derived from xestokerol B. The in vitro anti-proliferat

Cyclization into Hydrindanones Using Samarium Diiodide

Sono, Masakazu,Nakashiba, Yasuyo,Nakashima, Katsuyuki,Tori, Motoo

, p. 3099 - 3106 (2007/10/03)

Samarium(II) iodide has been employed to promote vinylogous pinacol coupling reaction of aldehyde onto α,β-unsaturated ketones. The diastereoselectivity of 6-endo products was changed by addition of a proton source and/or HMPA and by the reaction temperature. The cyclization reactions described herein provide a general approach to the syntheses of 3,3-dimethylhydrindanes with a cis-relationship between the OH at C-4 and the proton at C-3a with good diastereoselectivity and under mild reaction conditions.
