Check Digit Verification of cas no

The CAS Registry Mumber 1262222-89-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,2,2 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1262222-89:
(9*1)+(8*2)+(7*6)+(6*2)+(5*2)+(4*2)+(3*2)+(2*8)+(1*9)=128
128 % 10 = 8
So 1262222-89-8 is a valid CAS Registry Number.

Tirucallane triterpenoids from cornus walteri

Kim, Ki Hyun,Choi, Sang Un,Kim, Young Choong,Lee, Kang Ro

, p. 54 - 59 (2011)

Twelve new tirucallane triterpenoids, named cornusalterins A-L (1-12), and two known tirucallane triterpenoids, deoxyflindissone (13) and (-)-leucophyllone (14), were isolated from a MeOH extract of stems and stem bark of Cornus walteri. The structures of the new compounds were determined by spectroscopic methods, including 1D and 2D NMR analyses. Compounds 12 and 13, possessing a tetrahydrofuran ring in the side chain, exhibited significant cytotoxic activity against the A549, SK-OV-3, SK-MEL-2, and XF498 cell lines.
