Check Digit Verification of cas no

The CAS Registry Mumber 120615-46-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,6,1 and 5 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 120615-46:
(8*1)+(7*2)+(6*0)+(5*6)+(4*1)+(3*5)+(2*4)+(1*6)=85
85 % 10 = 5
So 120615-46-5 is a valid CAS Registry Number.

Complementary facial selectivity in conjugate additions to γ-hydroxyenones

Swiss,Hinkley,Maryanoff,Liotta

, p. 127 - 131 (2007/10/02)

Complementary facial selectivity can be achieved in conjugate additions to γ-hydroxyenones by using either Grignard reagents or cuprates. In the case of the former, preliminary complexation of the magnesium reagent with the resident alkoxide, followed by alkyl group transfer, results in the exclusive formation of the syn product. Conversely, cuprate conjugate additions proceed in an anti fashion, presumably because, in this mode of addition, coulombic repulsions are minimized.
