Check Digit Verification of cas no

The CAS Registry Mumber 2139-93-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,3 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2139-93:
(6*2)+(5*1)+(4*3)+(3*9)+(2*9)+(1*3)=77
77 % 10 = 7
So 2139-93-7 is a valid CAS Registry Number.

Azides. Part VIII. Thermolysis of ethyl azidoformate in acetic and propionic anhydrides: facilitation of intramolecular cyclization of the resultant carbethoxynitrene to 2-oxazolidinone

Ayyangar, N. R.,Brahme, K. C.,Srinivasan, K. V.

, p. 1463 - 1468 (2007/10/02)

The thermolysis of ethyl azidoformate in acetic and propionic anhydrides as solvent yielded the corresponding N-acyl-2-oxazolidinones (2a,b) in relatively significant yields.The other major products isolated were N-carboxyethyl-N,O-diacyl hydroxylamine (1a.b) and N,N,O-triacetyl hydroxylamine (3).The intramolecular cyclization is facilitated by the solvent.
