Uses
Rigosertib (ON-01910) is a non-ATP-competitive inhibitor of Polo-like kinase 1 (PLK1).
Biological Activity
rigosertib (on-01910,estybon) is a potent, specific plk1 inhibitor with ic50 value of 9nm. rigosertib strongly inhibited the proliferation of cancer cell lines, with observed ic50 values in the nanomolar range for both hela (115 nm) and c33a (45 nm) cells. in contrast, rigosertib had a minimal effect on normal cell lines, bj and ect1/e6e7 (ic50 > 0.1 mm) [1]hela and c33a cells demonstrated a complete (>95%) g2/m arrest at concentrations of rigosertib >0.5 μm, whereas atrigosertib has been reported to be a more potent radiosensitizer than cisplatin in vivo [1].

Check Digit Verification of cas no
The CAS Registry Mumber 1225497-78-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,5,4,9 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1225497-78:
(9*1)+(8*2)+(7*2)+(6*5)+(5*4)+(4*9)+(3*7)+(2*7)+(1*8)=168
168 % 10 = 8
So 1225497-78-8 is a valid CAS Registry Number.
