Check Digit Verification of cas no
The CAS Registry Mumber 149981-23-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,9,8 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 149981-23:
(8*1)+(7*4)+(6*9)+(5*9)+(4*8)+(3*1)+(2*2)+(1*3)=177
177 % 10 = 7
So 149981-23-7 is a valid CAS Registry Number.

Effect of Trifluoromethyl and Other Substituents on Activity of Xanthines at Adenosine Receptors
Jacobson, Kenneth A.,Shi, Dan,Gallo-Rodriguez, Carola,Manning, Malcolm,Mueller, Christa,et al.
, p. 2639 - 2644 (2007/10/02)
An aryl p-(trifluoromethyl) substituent increases the affinity of 1,3-disubstituted 8-phenylxanthines at A2a-adenosine receptors, while having little effect on affinity at A1-adenosine receptors.In contrast, an aryl p-(trifluoromethy
