Check Digit Verification of cas no

The CAS Registry Mumber 1297549-91-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,7,5,4 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1297549-91:
(9*1)+(8*2)+(7*9)+(6*7)+(5*5)+(4*4)+(3*9)+(2*9)+(1*1)=217
217 % 10 = 7
So 1297549-91-7 is a valid CAS Registry Number.

Fluorinated cyclopropanes: Synthesis and chemistry of the aryl α,β,β-trifluorocyclopropane motif

Thomson, Connor J.,Zhang, Qingzhi,Al-Maharik, Nawaf,Bühl, Michael,Cordes, David B.,Slawin, Alexandra M. Z.,O'Hagan, David

, p. 8415 - 8418 (2018)

A general route to aryl α,β,β-trifluorocyclopropanes is reported and aryl oxidation gave the corresponding α,β,β-trifluorocyclopropane carboxylic acid. Reactions of the corresponding amides with phenol/thiophenol resulted in HF elimination and then conjugate addition. The partially fluorinated cyclopropane has a similar lipophilicity to -CF3 despite three carbon atoms, and it emerges as a novel motif for drug discovery.
