123381-13-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123381-13-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,3,8 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 123381-13:
(8*1)+(7*2)+(6*3)+(5*3)+(4*8)+(3*1)+(2*1)+(1*3)=95
95 % 10 = 5
So 123381-13-5 is a valid CAS Registry Number.

The stereospecific preparation of a hydroxyethylene isostere precursor via a novel piperidine-2,5-dione template
Plata,Leanna,Morton
, p. 3623 - 3626 (2007/10/02)
Hydroxyethylene isostere precursor 2 was synthesized by stereochemical manipulation of a novel ketolactam 'template'. The final product was prepared in very high enantiomeric purity, in 23% overall yield from L-phenylalanine.
