38499-45-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 38499-45-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,4,9 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 38499-45:
(7*3)+(6*8)+(5*4)+(4*9)+(3*9)+(2*4)+(1*5)=165
165 % 10 = 5
So 38499-45-5 is a valid CAS Registry Number.

SmI2-promoted imino-Reformatsky reaction for facile synthesis of enantioenriched β-amino acid esters

Wang, Li,Shen, Chun,Xu, Ming-Hua

experimental part, p. 61 - 65 (2011/12/15)

A facile and efficient method for the stereoselective synthesis of β-amino acid esters via SmI2-promoted imino-Reformatsky reaction is described. Asymmetric addition of tert-butyl bromoacetate to N-tert-butanesulfinyl aldimines afforded β-amino
