99697-85-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99697-85-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,6,9 and 7 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 99697-85:
(7*9)+(6*9)+(5*6)+(4*9)+(3*7)+(2*8)+(1*5)=225
225 % 10 = 5
So 99697-85-5 is a valid CAS Registry Number.

, p. 1509 - 1512 (2007/10/02)
New mono- and di-substituted 3-aza-α-tropolones 6 were synthesized by deethoxycarbonylation and subsequent DDQ oxidation of dihydroazatropolones 4.In methanol, 6 undergoes a skeletal rearrangement to give methyl pyridine-2-carboxylates 7, suggesting that
