Check Digit Verification of cas no

The CAS Registry Mumber 13694-42-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,6,9 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 13694-42:
(7*1)+(6*3)+(5*6)+(4*9)+(3*4)+(2*4)+(1*2)=113
113 % 10 = 3
So 13694-42-3 is a valid CAS Registry Number.

Kinetic resolution of hydroperoxides with enantiopure phosphines: Preparation of enantioenriched tertiary hydroperoxides

Driver, Tom G.,Harris, Jason R.,Woerpel

, p. 3836 - 3837 (2008/02/13)

An efficient reductive kinetic resolution strategy capable of accessing optically active tertiary hydroperoxides is reported. Readily accessible tertiary hydroperoxides are resolved with commercially available (R)- or (S)-xylyl-PHANEPHOS with selectivity factors as large as 37. The resulting bis(phosphine oxide) can be recycled in high yields. The isolated mono(phosphine oxide) intermediate resolved hydroperoxides with the same selectivity as the parent bisphosphine.
