145681-30-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145681-30-7 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, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 145681-30:
(8*1)+(7*4)+(6*5)+(5*6)+(4*8)+(3*1)+(2*3)+(1*0)=137
137 % 10 = 7
So 145681-30-7 is a valid CAS Registry Number.

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
