Check Digit Verification of cas no

The CAS Registry Mumber 844498-77-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,4,4,9 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 844498-77:
(8*8)+(7*4)+(6*4)+(5*4)+(4*9)+(3*8)+(2*7)+(1*7)=217
217 % 10 = 7
So 844498-77-7 is a valid CAS Registry Number.

The discovery of a selective, high affinity A2B adenosine receptor antagonist for the potential treatment of asthma

Zablocki, Jeff,Kalla, Rao,Perry, Thao,Palle, Venkata,Varkhedkar, Vaibhav,Xiao, Dengming,Piscopio, Anthony,Maa, Tenning,Gimbel, Art,Hao, Jia,Chu, Nancy,Leung, Kwan,Zeng, Dewan

, p. 609 - 612 (2007/10/03)

Adenosine has been suggested to play a role in asthma, possibly via activation of A2B adenosine receptors on mast cells and other pulmonary cells. We describe our initial efforts to discover a xanthine based selective A2B AdoR antagonist that resulted in the discovery of CVT-5440, a high affinity A2B AdoR antagonist with good selectivity (A2B AdoR Ki = 50 nM, selectivity A1 > 200: A2A > 200: A3 > 167).
