Check Digit Verification of cas no
The CAS Registry Mumber 165676-63-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,5,6,7 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 165676-63:
(8*1)+(7*6)+(6*5)+(5*6)+(4*7)+(3*6)+(2*6)+(1*3)=171
171 % 10 = 1
So 165676-63-1 is a valid CAS Registry Number.

Reaction of 4-Hydroxy-5-oximino-3-thiophenecarboxylates with Hydrazines. Formation of Pyrazolylthiohydroxamic Acids
Robey,Alt,Van Meter
, p. 413 - 428 (2007/10/03)
The reactions of 4-hydroxy-5-oximino-3-thiophenecarboxylates with hydrazine and substituted hydrazines have been investigated. The products of the reactions have been shown to be pyrazole-3- or 5-thiohydroxamic acids rather than the hydrazones previously described by Benary and Silberstrom. Two alternate mechanisms are proposed which account for the regiochemical outcome. The structures of the pyrazole-3- and 5-thiohydroxamic acids and corresponding nitriles have been proven by independent synthesis, comparison to known compounds, and by proton and carbon magnetic resonance and long range HETCOR experiments.
