Check Digit Verification of cas no

The CAS Registry Mumber 771580-80-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,1,5,8 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 771580-80:
(8*7)+(7*7)+(6*1)+(5*5)+(4*8)+(3*0)+(2*8)+(1*0)=184
184 % 10 = 4
So 771580-80-4 is a valid CAS Registry Number.

Catechols and 3-hydroxypyridones as inhibitors of the DNA repair complex ERCC1-XPF

Catechol-based inhibitors of ERCC1-XPF endonuclease activity were identified from a high-throughput screen. Exploration of the structure-activity relationships within this series yielded compound 13, which displayed an ERCC1-XPF IC50 of 0.6 μM, high selectivity against FEN-1 and DNase I and activity in nucleotide excision repair, cisplatin enhancement and γH2AX assays in A375 melanoma cells. Screening of fragments as potential alternatives to the catechol group revealed that 3-hydroxypyridones are able to inhibit ERCC1-XPF with high ligand efficiency, and elaboration of the hit gave compounds 36 and 37 which showed promising ERCC1-XPF IC50 values of 10 μM.
