Check Digit Verification of cas no

The CAS Registry Mumber 1187193-67-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,7,1,9 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1187193-67:
(9*1)+(8*1)+(7*8)+(6*7)+(5*1)+(4*9)+(3*3)+(2*6)+(1*7)=184
184 % 10 = 4
So 1187193-67-4 is a valid CAS Registry Number.

Highly selective iridium-catalyzed asymmetric hydrogenation of trifluoromethyl olefins: A new route to trifluoromethyl-bearing stereocenters

Engman, Mattias,Cheruku, Pradeep,Tolstoy, Paeivi,Bergquist, Jonas,Voelker, Sebastian F.,Andersson, Pher G.

, p. 375 - 378 (2009)

Fluorine-containing compounds are useful in many applications ranging from pharmaceuticals to ferroelectric crystals. We have developed a new, highly enantioselective synthetic route to trifluoromethyl-bearing stereocenters in up to 96% ee via asymmetric hydrogenation using N,P-ligated iridium catalysts. We also hydrogenated an isomeric mixture of olefins; this reaction gave the hydrogenation product highly enantioselectively (87% ee), and only the E isomer was present after the reaction had reached 56% conversion.
