23521-81-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 23521-81-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,5,2 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 23521-81:
(7*2)+(6*3)+(5*5)+(4*2)+(3*1)+(2*8)+(1*1)=85
85 % 10 = 5
So 23521-81-5 is a valid CAS Registry Number.

Design, synthesis and SAR study of bridged tricyclic pyrimidinone carboxamides as HIV-1 integrase inhibitors

supporting information, (2020/05/18)

The design, synthesis and structure-activity relationships associated with a series of bridged tricyclic pyrimidinone carboxamides as potent inhibitors of HIV-1 integrase strand transfer are described. Structural modifications to these molecules were made in order to examine the effect on potency towards wild-type and clinically-relevant resistant viruses. The [3.2.2]-bridged tricyclic system was identified as an advantageous chemotype, with representatives exhibiting excellent antiviral activity against both wild-type viruses and the G140S/Q148H resistant virus that arises in response to therapy with raltegravir and elvitegravir.
