159855-51-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159855-51-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,8,5 and 5 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 159855-51:
(8*1)+(7*5)+(6*9)+(5*8)+(4*5)+(3*5)+(2*5)+(1*1)=183
183 % 10 = 3
So 159855-51-3 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
