Compound 3 was dissolved in ethanol,Potassium hydroxide was added and refluxed at 78 ° C for 4 h,After cooling to room temperature (25 ° C), the reaction solution was extracted with IM HCl, extracted with ethyl acetate, dried over Mg2SO4 and dried to give the title compound 4 (92%).
Check Digit Verification of cas no
The CAS Registry Mumber 7712-05-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,1 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7712-05:
(6*7)+(5*7)+(4*1)+(3*2)+(2*0)+(1*5)=92
92 % 10 = 2
So 7712-05-2 is a valid CAS Registry Number.
