Check Digit Verification of cas no
The CAS Registry Mumber 40568-81-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,5,6 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 40568-81:
(7*4)+(6*0)+(5*5)+(4*6)+(3*8)+(2*8)+(1*1)=118
118 % 10 = 8
So 40568-81-8 is a valid CAS Registry Number.

An efficient route to chiral α- and β-hydroxyalkanephosphonates
Pamies, Oscar,Baeckvall, Jan-E.
, p. 4815 - 4818 (2007/10/03)
Enzymatic kinetic resolution of α- and β-hydroxyphosphonates in combination with ruthenium-catalyzed alcohol isomerization led to a successful dynamic kinetic resolution. A variety of racemic hydroxyphosphonates were efficiently transformed to the corresponding enantiomerically pure acetates (ee up to 99% and yield up to 87%).
