680974-84-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 680974-84-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,0,9,7 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 680974-84:
(8*6)+(7*8)+(6*0)+(5*9)+(4*7)+(3*4)+(2*8)+(1*4)=209
209 % 10 = 9
So 680974-84-9 is a valid CAS Registry Number.

Efficient, stereoselective synthesis of trans-2,5-disubstituted morpholines
Lanman, Brian A.,Myers, Andrew G.
, p. 1045 - 1047 (2007/10/03)
(Equation presented) Enantio- and diastereoselective syntheses of trans-2,5-disubstituted morpholine derivatives are described. The routes are initiated by the reaction of enantiopure epoxides (2) with amino alcohols (3) and address the problem of regiose
