Check Digit Verification of cas no

The CAS Registry Mumber 1373311-25-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,3,3,1 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1373311-25:
(9*1)+(8*3)+(7*7)+(6*3)+(5*3)+(4*1)+(3*1)+(2*2)+(1*5)=131
131 % 10 = 1
So 1373311-25-1 is a valid CAS Registry Number.

Cushing's syndrome: Development of highly potent and selective CYP11B1 inhibitors of the (pyridylmethyl)pyridine type

Emmerich, Juliette,Hu, Qingzhong,Hanke, Nina,Hartmann, Rolf W.

, p. 6022 - 6032 (2013/09/02)

Potent and selective CYP11B1 inhibitors could be promising therapeutics for the treatment of Cushing's syndrome. Optimization of Ref 1 (5-((1H-imidazol-1- yl)methyl)-2-phenylpyridine) led to compound 44 (5-((5-methylpyridin-3-yl) methyl)-2-phenylpyridine) with a 50-fold improved IC50 value of 2 nM toward human CYP11B1 and an enhanced inhibition of the rat enzyme (IC 50 = 2440 nM) compared to Ref 1 (IC50 > 10000 nM). Furthermore, selectivities over CYP11B2, CYP17, and CYP19 were observed, as well as satisfying metabolic stability not only in human and rat plasma but also in liver S9 fraction. Investigation of cytotoxicity and inhibition of hepatic CYP2A6 and CYP3A4 showed that 44 fulfills first safety criteria and can be considered for further in vivo evaluation in rats.
