Check Digit Verification of cas no
The CAS Registry Mumber 38835-18-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,8,3 and 5 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 38835-18:
(7*3)+(6*8)+(5*8)+(4*3)+(3*5)+(2*1)+(1*8)=146
146 % 10 = 6
So 38835-18-6 is a valid CAS Registry Number.

Lewis acid-induced internal proton return in enolate complexes with chiral amines
Vedejs, Edwin,Lee, Namkyu
, p. 891 - 899 (2007/10/02)
Treatment of a 1:1:1 mixture of enolate 5:amine 6:lithium amide 7 with BF3·OEt2 affords the naproxen amide 4a with an enantiomer excess of 77% (>90% yield). The result is attributed to Lewis acid-induced internal proton return (ipr)
