138944-02-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138944-02-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,4 and 4 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138944-02:
(8*1)+(7*3)+(6*8)+(5*9)+(4*4)+(3*4)+(2*0)+(1*2)=152
152 % 10 = 2
So 138944-02-2 is a valid CAS Registry Number.

Stereoselective addition of methyl acrylate to α-amino aldehydes
Manickum,Roos
, p. 2269 - 2274 (2007/10/02)
Variously N-protected α-aminoaldehydes exhibit reasonable diastereoselectivity in the Baylis-Hillman coupling with methyl acrylate to provide either primarily syn or anti α-methylene-β-hydroxy-γ-amino esters.
