Check Digit Verification of cas no

The CAS Registry Mumber 1352758-14-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,2,7,5 and 8 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1352758-14:
(9*1)+(8*3)+(7*5)+(6*2)+(5*7)+(4*5)+(3*8)+(2*1)+(1*4)=165
165 % 10 = 5
So 1352758-14-5 is a valid CAS Registry Number.

Chiral dihydrobenzo[1,4]oxazines as catalysts for the asymmetric transfer-hydrogenation of α,β-unsaturated aldehydes

Ebner, Christian,Pfaltz, Andreas

, p. 10287 - 10290 (2011)

A new class of organocatalysts based on the structure of 2,3-dihydrobenzo[1,4]oxazine was prepared and applied in the enantioselective transfer-hydrogenation of α,β-unsaturated aldehydes with Hantzsch ester as hydride donor. These catalysts proved to be particularly effective for the conjugate reduction of β,β-diaryl-substituted acrylaldehydes leading to saturated aldehydes bearing a stereogenic center with two different aryl groups with enantioselectivities of up to 91% ee.
