Check Digit Verification of cas no

The CAS Registry Mumber 115441-65-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,4,4 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 115441-65:
(8*1)+(7*1)+(6*5)+(5*4)+(4*4)+(3*1)+(2*6)+(1*5)=101
101 % 10 = 1
So 115441-65-1 is a valid CAS Registry Number.

Isolation, structural elucidation, and synthesis of RA-XVII, a novel bicyclic hexapeptide from Rubia cordifolia, and the effect of side chain at residue 1 upon the conformation and cytotoxic activity

Hitotsuyanagi, Yukio,Ishikawa, Hiroshi,Hasuda, Tomoyo,Takeya, Koichi

, p. 935 - 938 (2004)

A novel antitumor bicyclic hexapeptide RA-XVII was isolated from the roots of Rubia cordifolia. By spectral studies and synthetic approach, its structure was determined to be [D-2-aminobutyric acid-1]deoxybouvardin. Studies on the effect of side chain at

Regioselective synthesis of 14-membered biaryl ethers: Total synthesis of RA-VII and deoxybouvardin

, p. 1325 - 1335 (2007/10/02)

In order to obtain a key compound (22a'') for synthesis of RA-VII (1) and deoxybouvardin (2), construction of the 14-membered ring system was performed by means of thallium trinitrate-mediated oxidation of the tetrahalogeno amides 5-7. The dibromo dichlor
