Check Digit Verification of cas no

The CAS Registry Mumber 1238056-79-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,8,0,5 and 6 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1238056-79:
(9*1)+(8*2)+(7*3)+(6*8)+(5*0)+(4*5)+(3*6)+(2*7)+(1*9)=155
155 % 10 = 5
So 1238056-79-5 is a valid CAS Registry Number.

Synthesis and cytotoxicity of novel indirubin-5-carboxamides

Cheng, Xinlai,Rasque, Paul,Vatter, Sandra,Merz, Karl-Heinz,Eisenbrand, Gerhard

experimental part, p. 4509 - 4515 (2010/08/22)

Indirubins have been reported to act as potent inhibitors of protein kinases relevant to tumorigenesis and of tumor cell growth, but their development to antitumor drugs suffer from their poor water solubility. We synthesized a novel class of indirubin derivatives, indirubin-5-carboxamides, carrying amide substituents with basic centers. Quaternization or protonation of these alkylamino substituents provided indirubins with significantly improved solubility without loss of bioactivity.
