Check Digit Verification of cas no

The CAS Registry Mumber 1027059-42-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,0,5 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1027059-42:
(9*1)+(8*0)+(7*2)+(6*7)+(5*0)+(4*5)+(3*9)+(2*4)+(1*2)=122
122 % 10 = 2
So 1027059-42-2 is a valid CAS Registry Number.

Structure-antitumor activity relationship of semi-synthetic spicamycin derivatives

Sakai,Kawai,Kamishohara,Odagawa,Suzuki,Uchida,Kawasaki,Tsuruo,Otake

, p. 1467 - 1480 (2007/10/03)

New derivatives of spicamycin modified at the fatty acid moieties of the molecule were synthesized and their structure-activity relationships were examined. The antitumor activity was greatly influenced by modification of the fatty acid moieties to tetradecadienoyl or dodecadienoyl analogues exhibiting better antitumor activity against COL-1 human colon cancer xenograft than SPM VIII.
