Check Digit Verification of cas no

The CAS Registry Mumber 422566-49-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,2,5,6 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 422566-49:
(8*4)+(7*2)+(6*2)+(5*5)+(4*6)+(3*6)+(2*4)+(1*9)=142
142 % 10 = 2
So 422566-49-2 is a valid CAS Registry Number.

Synthesis and structure-activity relationship study of lamellarin derivatives

Ishibashi, Fumito,Tanabe, Shinji,Oda, Tatsuya,Iwao, Masatomo

, p. 500 - 504 (2007/10/03)

Ten derivatives (3-12) of marine alkaloid lamellarin D (1) were synthesized and evaluated for cytotoxicity against a HeLa cell line in an effort to examine their structure-activity relationships. It appeared that the hydroxyl groups at positions C-8 and C-20 of 1 were important structural requirements for cytotoxic activity, while the hydroxyl group at C-14 and the two methoxy groups at C-13 and C-21 were not necessary for the activity.
