Check Digit Verification of cas no

The CAS Registry Mumber 1189811-71-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,8,1 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1189811-71:
(9*1)+(8*1)+(7*8)+(6*9)+(5*8)+(4*1)+(3*1)+(2*7)+(1*1)=189
189 % 10 = 9
So 1189811-71-9 is a valid CAS Registry Number.

Rational design of phosphoinositide 3-kinase inhibitors that exhibit selectivity over the phosphoinositide 3-kinase isoform

Heffron, Timothy P.,Wei, Binqing,Olivero, Alan,Staben, Steven T.,Tsui, Vickie,Do, Steven,Dotson, Jennafer,Folkes, Adrian J.,Goldsmith, Paul,Goldsmith, Richard,Gunzner, Janet,Lesnick, John,Lewis, Cristina,Mathieu, Simon,Nonomiya, Jim,Shuttleworth, Stephen,Sutherlin, Daniel P.,Wan, Nan Chi,Wang, Shumei,Wiesmann, Christian,Zhu, Bing-Yan

experimental part, p. 7815 - 7833 (2012/01/05)

Of the four class I phosphoinositide 3-kinase (PI3K) isoforms, PI3K has justly received the most attention for its potential in cancer therapy. Herein we report our successful approaches to achieve PI3K vs PI3K selectivity for two chemical series. In the thienopyrimidine series of inhibitors, we propose that select ligands achieve selectivity derived from a hydrogen bonding interaction with Arg770 of PI3K that is not attained with the corresponding Lys777 of PI3K. In the benzoxepin series of inhibitors, the selectivity observed can be rationalized by the difference in electrostatic potential between the two isoforms in a given region rather than any specific interaction.
