Check Digit Verification of cas no

The CAS Registry Mumber 145681-43-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,6,8 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 145681-43:
(8*1)+(7*4)+(6*5)+(5*6)+(4*8)+(3*1)+(2*4)+(1*3)=142
142 % 10 = 2
So 145681-43-2 is a valid CAS Registry Number.

Asymmetric Epoxidation and Kinetic Resolution of Allylic Phosphine Oxides

Clayden, Jonathan,Warren, Stuart

, p. 2811 - 2824 (2007/10/02)

Allylic alcohols bearing a diphenylphosphinoyl group undergo asymmetric epoxidation with excellent enantioselectivity, and can undergo kinetic resolution with good diastereoselectivity, with the diphenylphosphinoyl group exerting an anti-directing effect

Asymmetric epoxidations and kinetic resolutions of δ-hydroxy allylic phosphine oxides

Clayden,Collington,Warren

, p. 7043 - 7046 (2007/10/02)

δ-Hydroxy allylic phosphine oxides 5 undergo asymmetric epoxidation to yield epoxy alcohols 6 with high enantio- and diastereoselectivity. Kinetic resolutions are also successful, even with a chiral centre remote from the allylic hydroxyl, if that chiral
