Check Digit Verification of cas no

The CAS Registry Mumber 1310802-74-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,0,8,0 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1310802-74:
(9*1)+(8*3)+(7*1)+(6*0)+(5*8)+(4*0)+(3*2)+(2*7)+(1*4)=104
104 % 10 = 4
So 1310802-74-4 is a valid CAS Registry Number.

Asymmetric synthesis of (-)-chicanine using a highly regioselective intramolecular Mitsunobu reaction and revision of its absolute configuration

Harada, Kenichi,Horiuchi, Hiroki,Tanabe, Kazuma,Carter, Rich G.,Esumi, Tomoyuki,Kubo, Miwa,Hioki, Hideaki,Fukuyama, Yoshiyasu

, p. 3005 - 3008 (2011/06/23)

First asymmetric synthesis of (-)-chicanine has been accomplished in 14 steps by employing the Evans asymmetric syn-selective aldol reaction, diastereoselective hydroboration and an regioselective, intramolecular Mitsunobu etherification. The absolute configuration of (+)- and (-)-chicanine has been revised to 2R,3S,4R,5R and 2S,3R,4S,5S, respectively, through CD analysis.
