Check Digit Verification of cas no

The CAS Registry Mumber 1448582-17-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,8,5,8 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1448582-17:
(9*1)+(8*4)+(7*4)+(6*8)+(5*5)+(4*8)+(3*2)+(2*1)+(1*7)=189
189 % 10 = 9
So 1448582-17-9 is a valid CAS Registry Number.

Enantioselective direct α-amination of aldehydes via a photoredox mechanism: A strategy for asymmetric amine fragment coupling

Cecere, Giuseppe,Koenig, Christian M.,Alleva, Jennifer L.,MacMillan, David W. C.

, p. 11521 - 11524 (2013/09/02)

The direct, asymmetric α-amination of aldehydes has been accomplished via a combination of photoredox and organocatalysis. Photon-generated N-centered radicals undergo enantioselective α-addition to catalytically formed chiral enamines to directly produce stable α-amino aldehyde adducts bearing synthetically useful amine substitution patterns. Incorporation of a photolabile group on the amine precursor obviates the need to employ a photoredox catalyst in this transformation. Importantly, this photoinduced transformation allows direct and enantioselective access to α-amino aldehyde products that do not require postreaction manipulation.
