103829-05-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 103829-05-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,8,2 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 103829-05:
(8*1)+(7*0)+(6*3)+(5*8)+(4*2)+(3*9)+(2*0)+(1*5)=106
106 % 10 = 6
So 103829-05-6 is a valid CAS Registry Number.

Synthesis and antitumor activities of novel benzoylphenylurea derivatives
Okada,Koyanagi,Yamada,Haga
, p. 2308 - 2315 (2007/10/02)
Seventy novel benzoylphenylurea compounds were synthesized and their antitumor activities were examined in vivo against P388 leukemia. N-(2-Nitrobenzoyl)-N'-[4-(2-pyrimidinyloxy)phenyl]ureas showed the highest antitumor activities when dosed intraperitoneally or orally. Their structure-activity relationships were examined with particular focus on the position and the variety of substituent on each aryl ring.
