Check Digit Verification of cas no

The CAS Registry Mumber 1142247-91-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,2,2,4 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1142247-91:
(9*1)+(8*1)+(7*4)+(6*2)+(5*2)+(4*4)+(3*7)+(2*9)+(1*1)=123
123 % 10 = 3
So 1142247-91-3 is a valid CAS Registry Number.

Mapping the mechanism of nickel-ferrophite catalysed methylation of baylis-hillman-derived SN2′ electrophiles

Novak, Andrew,Calhorda, Maria Jose,Costa, Paulo Jorge,Woodward, Simon

experimental part, p. 898 - 903 (2009/07/19)

Enantioselective Ni-catalysed methylation of Baylis-Hillman-derived allylic electrophiles in the presence of ferrophite ligands has been investigated computationally and experimentally. The sense and degree of enantioselectivity attained is independent of both the leaving group and the isomeric structure of the initial allylic halide. DFT studies support the selective formation of a limited number of energetically favoured anti and syn π-allyl intermediates. The observed regio- and enantioselectivity can be rationalised based on the energetics of these structures.
