179863-13-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 179863-13-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,9,8,6 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 179863-13:
(8*1)+(7*7)+(6*9)+(5*8)+(4*6)+(3*3)+(2*1)+(1*3)=189
189 % 10 = 9
So 179863-13-9 is a valid CAS Registry Number.

A novel synthetic route to morpholin-2,3-diones from 2-aminoalcohols
Harwood, Laurence M.,Tucker, Toby T.,Angell, Richard,Finch, Harry
, p. 4217 - 4220 (2007/10/03)
Reaction of dimethyl acetylenedicarboxylate with 2-aminoalcohols possessing a primary amino group gives 3- methoxycarbonylmethylidinemorpholin-2-ones 5. Subsequent ozonolysis furnishes morpholin-2,3-diones 1 in excellent yields.
