Check Digit Verification of cas no
The CAS Registry Mumber 127020-20-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,0,2 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 127020-20:
(8*1)+(7*2)+(6*7)+(5*0)+(4*2)+(3*0)+(2*2)+(1*0)=76
76 % 10 = 6
So 127020-20-6 is a valid CAS Registry Number.

Synthesis of 3-ethoxyisoxazole derivatives and 3-ethoxy-1H-pyrazole derivatives from β-oxo thionoesters
Ohta,Fujisawa,Nakai,Furukawa

3-Ethoxyisoxazoles and 3-ethoxy-1H-pyrazoles were obtained in high yields from β-oxo thionoesters. The reaction of the ethyl β-oxo thionoesters with hydroxylamine hydrochloride in the presence of triethylamine at room temperature for 2 h gave the ethyl 3-oxopropiohydroximates and their hemiacetals, which were easily converted to the 3-ethoxyisoxazoles by refluxing for 3 h at pH 3-5. On the other hand, the reaction of the ethyl β-oxo thionoesters with hydrazine derivatives in the presence of triethylamine for 3-8 h at room temperature directly yielded the 3-ethoxy-1H-pyrazoles.
