1544430-88-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1544430-88-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,4,4,4,3 and 0 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1544430-88:
(9*1)+(8*5)+(7*4)+(6*4)+(5*4)+(4*3)+(3*0)+(2*8)+(1*8)=157
157 % 10 = 7
So 1544430-88-7 is a valid CAS Registry Number.

Racemization-Free Synthesis of Morpholinone Derivatives from α-Amino Acids
Samanta, Sauvik,Mal, Abhijit,Halder, Sandipan,Ghorai, Manas K.
, p. 3776 - 3782 (2015)
A simple strategy is reported for the synthesis of chiral N-protected morpholinone derivatives by a base (potassium carbonate)-mediated cyclization reaction of N-protected α-amino acids with 1,2-dibromoethane. The morpholinone derivatives are obtained in
