Check Digit Verification of cas no

The CAS Registry Mumber 1416255-30-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,6,2,5 and 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1416255-30:
(9*1)+(8*4)+(7*1)+(6*6)+(5*2)+(4*5)+(3*5)+(2*3)+(1*0)=135
135 % 10 = 5
So 1416255-30-5 is a valid CAS Registry Number.

Aryl hetaryl ketones and thioketones as efficient inhibitors of peptidyl-prolyl cis-trans isomerases

Hediger, Thomas,Frank, Walter,Schumann, Michael,Fischer, Gunter,Braun, Manfred

, p. 2618 - 2634 (2013/01/16)

A series of 18 differently substituted new aryl hetaryl ketones and thioketones were synthesized in four to six steps from commercial starting materials. The new ketones were evaluated as inhibitors of the peptidyl-prolyl cis-trans isomerase hPin1 with Ki values ranging in the one-digit micromolar to sub-micromolar numbers. A crystal structure revealed the non-planar arrangement of the aryl residues at the carbonyl compound and supports the hypothesis that the new compounds might mimic the transition state of the enzymatic conversion.
