Check Digit Verification of cas no

The CAS Registry Mumber 557091-48-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,7,0,9 and 1 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 557091-48:
(8*5)+(7*5)+(6*7)+(5*0)+(4*9)+(3*1)+(2*4)+(1*8)=172
172 % 10 = 2
So 557091-48-2 is a valid CAS Registry Number.

Reaction of 3,3-dichloro-2-dichloroacetylaminoacrylonitrile with amines

Pil'o,Brovarets,Romanenko,Drach

, p. 1724 - 1729 (2007/10/03)

Polychlorinated enamidonitrile Cl2C=C(CN)NHCOCHCl2 readily reacts with primary aromatic amines, dialkylamines, piperidine, and morpholine. The reaction is accompanied by complete elimination of chlorine atoms as chloride ions with formation of 4-cyanooxazoles having the corresponding amine residue in position 5 of the ring and a CH=N or diaminomethyl moiety in position 2. The structure of 5-arylamino-(dialkylamino)-4-cyano-2-formyloxazoles was confirmed by their acid hydrolysis, as well as by the condensation with phenylhydrazine, N-alkylrhodanines, and ethyl acetoacetate in the presence of urea.
