Check Digit Verification of cas no
The CAS Registry Mumber 57646-87-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,6,4 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 57646-87:
(7*5)+(6*7)+(5*6)+(4*4)+(3*6)+(2*8)+(1*7)=164
164 % 10 = 4
So 57646-87-4 is a valid CAS Registry Number.

The reaction of N,N-dichloroacetamide and N,N-dichlorobenzamide with trichloroethylene in an inert atmosphere leads to the formation of the products from the transformation of the corresponding acylimines of chloral, i.e. 2,2,2-trichloro-1,1-di(acetamido)benzamido ethanes, N-(2,2,2-trichloro-1-hydroxyethyl)acetamides and the corresponding benzamides, and pentachloroethane.In the reaction of N,N-dichlorobenzamide with trichloroethylene in the presence of atmospheric oxygen N-(dichloroacetyl)benzamide is obtained in additon to N-(2,2,2-trichloro-1-hydroxyethyl)benzamide and pentachloroethane.Its formation results from the parallel processes of oxidation of the trichloroethylene to dichloroacetyl chloride and reduction of the dichlorobenzamide to benzamide and their reaction.
