Check Digit Verification of cas no

The CAS Registry Mumber 82245-97-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,2,4 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 82245-97:
(7*8)+(6*2)+(5*2)+(4*4)+(3*5)+(2*9)+(1*7)=134
134 % 10 = 4
So 82245-97-4 is a valid CAS Registry Number.

Tautomerism in 2-Trichloro- and 2-Trifluoro-acetamidothiazoles

Birkinshaw, Timothy N.,Harkin, Shaun A.,Kaye, Perry T.,Meakins, G. Denis,Smith, Antony K.

, p. 939 - 944 (2007/10/02)

Series of new 4- and 5-substituted thiazoles with acetamido-, mono-, di-and tri-chloroacetamido- , and tri-fluoroacetamido-groups at position 2 have been prepared.Amide-acylimine tautomerism in these compounds has been investigated by comparing their i.r. and u.v. spectra in carbon tetrachloride and in acetonitrile with those of related 2-N-methylacetamido- and 3-methyl-2-acetylimino-thiazoles.The trichloro- and trifluoro-acetamides exhibit tautomerism in both solvents; the acylimino-forms are most stable with the trifluoro-compounds in the more polar solvent.
