Check Digit Verification of cas no

The CAS Registry Mumber 1293388-28-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,3,3,8 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1293388-28:
(9*1)+(8*2)+(7*9)+(6*3)+(5*3)+(4*8)+(3*8)+(2*2)+(1*8)=189
189 % 10 = 9
So 1293388-28-9 is a valid CAS Registry Number.

Figure Presented. HIV-1 integrase (IN) is one of three enzymes encoded by the HIV genome and is essential for viral replication, and HIV-1 IN inhibitors have emerged as a new promising class of therapeutics. Recently, we reported the synthesis of orally bioavailable azaindole hydroxamic acids that were potent inhibitors of the HIV-1 IN enzyme. Here we disclose the design and synthesis of novel tricyclic N-hydroxy-dihydronaphthyridinones as potent, orally bioavailable HIV-1 integrase inhibitors displaying excellent ligand and lipophilic efficiencies.
