91392-63-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91392-63-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,3,9 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 91392-63:
(7*9)+(6*1)+(5*3)+(4*9)+(3*2)+(2*6)+(1*3)=141
141 % 10 = 1
So 91392-63-1 is a valid CAS Registry Number.

, p. 85 - 90 (2007/10/03)
The method of exhaustive methylation has been applied for investigating tautomeric stability and its temperature variation of 6-hydroxy-5-methyl-3- pyridazinone (1) and its N-phenyl derivative (2) - two model compounds chosen for studying tautomeric trans
