Check Digit Verification of cas no

The CAS Registry Mumber 1172117-25-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,2,1,1 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1172117-25:
(9*1)+(8*1)+(7*7)+(6*2)+(5*1)+(4*1)+(3*7)+(2*2)+(1*5)=117
117 % 10 = 7
So 1172117-25-7 is a valid CAS Registry Number.

Supramolecular control of selectivity in hydroformylation of vinyl arenes: Easy access to valuable β-aldehyde intermediates

Dydio, Pawel,Reek, Joost N. H.

, p. 3878 - 3882 (2013)

Go against the flow! A rationally designed regioselective hydroformylation catalyst, [Rh/L], in which noncovalent ligand-substrate interactions allow the unprecedented reversal of selectivity from the typical α-aldehyde to the otherwise unfavored product β-aldehyde, is reported. This catalytic system opens up novel and sustainable synthetic pathways to important intermediates for the fine-chemicals industry.
