Check Digit Verification of cas no
The CAS Registry Mumber 78685-70-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,6,8 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 78685-70:
(7*7)+(6*8)+(5*6)+(4*8)+(3*5)+(2*7)+(1*0)=188
188 % 10 = 8
So 78685-70-8 is a valid CAS Registry Number.

Photochemical and Thermal Reactions of Aromatic Schiff Bases
Tauer, Erich,Grellmann, Karl H.
, p. 4252 - 4258 (2007/10/02)
The photochemical and thermal reactions of aromatic Schiff bases (SB) prepared from o-aminophenol and aldehydes and from o-aminophenol and ketones are compared.All SB's are converted by light into the corresponding benzoxazolines.For the SB's derived from aldehydes, benzoxazoline formation is a prerequisite to convert them by a second photon into benzoxazoles.In some cases oxygen is not required for this second reaction step.SB's derived from ketones are converted into benzoxazoles by the absorption of just one photon, but only in the presence of oxygen and only if the aliphatic residue R1 of the N=C(R1R2) bridge contains at least two carbon atoms.A radical mechanism is proposed for this reaction.Benzoxazine formation is observed in some cases as a thermal side reaction.The photochemical reactions of the latter were also investigated.
