Check Digit Verification of cas no

The CAS Registry Mumber 1417654-15-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,7,6,5 and 4 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1417654-15:
(9*1)+(8*4)+(7*1)+(6*7)+(5*6)+(4*5)+(3*4)+(2*1)+(1*5)=159
159 % 10 = 9
So 1417654-15-9 is a valid CAS Registry Number.

Small molecule inhibitors of PCNA/PIP-box interaction suppress translesion DNA synthesis

Proliferating cell nuclear antigen (PCNA) is an essential component for DNA replication and DNA damage response. Numerous proteins interact with PCNA through their short sequence called the PIP-box to be promoted to their respective functions. PCNA supports translesion DNA synthesis (TLS) by interacting with TLS polymerases through PIP-box interaction. Previously, we found a novel small molecule inhibitor of the PCNA/PIP-box interaction, T2AA, which inhibits DNA replication in cells. In this study, we created T2AA analogues and characterized them extensively for TLS inhibition. Compounds that inhibited biochemical PCNA/PIP-box interaction at an IC50 a reporter plasmid that was globally damaged by cisplatin, suggesting that the inhibitors blocked the TLS that allows replication of the plasmid. PCNA inhibitors increased γH2AX induction and cell viability reduction mediated by cisplatin. Taken together, these findings suggest that inhibitors of PCNA/PIP-box interaction could chemosensitize cells to cisplatin by inhibiting TLS.
