Check Digit Verification of cas no

The CAS Registry Mumber 1291080-74-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,1,0,8 and 0 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1291080-74:
(9*1)+(8*2)+(7*9)+(6*1)+(5*0)+(4*8)+(3*0)+(2*7)+(1*4)=144
144 % 10 = 4
So 1291080-74-4 is a valid CAS Registry Number.

Selective activation of enantiotopic C(sp3)-hydrogen by means of chiral phosphoric acid: Asymmetric synthesis of tetrahydroquinoline derivatives

Mori, Keiji,Ehara, Kensuke,Kurihara, Kazuki,Akiyama, Takahiko

, p. 6166 - 6169 (2011/06/21)

Chiral phosphoric acid-catalyzed asymmetric C-H functionalization has been achieved. In this process, enantiotopic C(sp3)-hydrogen is selectively activated by chiral phosphoric acid to afford tetrahydroquinoline derivatives with excellent enantioselectivities (up to 97% ee).
