Check Digit Verification of cas no

The CAS Registry Mumber 1563187-43-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,3,1,8 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1563187-43:
(9*1)+(8*5)+(7*6)+(6*3)+(5*1)+(4*8)+(3*7)+(2*4)+(1*3)=178
178 % 10 = 8
So 1563187-43-8 is a valid CAS Registry Number.

Enantioselective Michael addition of cyclic ketones to nitroolefins catalyzed by a novel fluorine-insertion organocatalyst

Wang, Yanan,Jiang, Min,Liu, Jin-Tao

, p. 212 - 218 (2014)

A novel fluorine-insertion organocatalyst, which was designed based on the fluorine-ammonium ion gauche effect, was synthesized and used successfully to catalyze the asymmetric Michael addition of cyclic ketones to nitroolefins. High yields and excellent diastereo- and enantioselectivities were achieved under mild conditions. A possible stereochemical model is also proposed.
