Check Digit Verification of cas no

The CAS Registry Mumber 133915-22-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,9,1 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 133915-22:
(8*1)+(7*3)+(6*3)+(5*9)+(4*1)+(3*5)+(2*2)+(1*2)=117
117 % 10 = 7
So 133915-22-7 is a valid CAS Registry Number.

Synthesis and potential antiallergic activity of new pteridinones and related compounds

Ferrand,Dumas,Depin,Quentin

, p. 273 - 280 (2007/10/03)

The synthesis and pharmacological profile of a series of 2-alkoxy and 2-phenoxymethyl-3H-pteridin-4-ones and related compounds are described. These compounds displayed antiallergic activity in the passive cutaneous anaphylaxis test in rats. In contrast to both sodium cromoglycate and nedocromil sodium, many of our compounds were active when administered orally. The most potent in this series, 2-ethoxymethyl-3H-pteridin-4-one 2b (LCB 2183) was investigated in other models of allergy and inflammation. The antiallergic activity was confirmed and interesting antiinflammatory properties were observed. It was therefore selected for further development as a human therapeutic agent.
