80305-77-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80305-77-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,3,0 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 80305-77:
(7*8)+(6*0)+(5*3)+(4*0)+(3*5)+(2*7)+(1*7)=107
107 % 10 = 7
So 80305-77-7 is a valid CAS Registry Number.

, p. 2110 - 2115 (2007/10/02)
4-Ethoxycarbonylmethylene-4,5-dihydrotetrazoloquinoxaline and itsα-substituted derivative display ketimine-enamine tautomeric isomerism.Their IR spectra and hydrazinolysis of 3,4-dihydro-3-oxo-quinoxaline analogues and related substances were studied.
