Check Digit Verification of cas no
The CAS Registry Mumber 7554-67-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,5 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7554-67:
(6*7)+(5*5)+(4*5)+(3*4)+(2*6)+(1*7)=118
118 % 10 = 8
So 7554-67-8 is a valid CAS Registry Number.

Nitrogen-containing heterocycles from metal β-diketonates
Svistunova,Shapkin,Nikolaeva,Apanasenko
experimental part, p. 756 - 761 (2011/08/06)
Factors determining the reaction of metal β-diketonates with hydrazine, in particular the nature of central metal ion and structure of β-diketonate ligand, are discussed. The possibility for the preparation of other heterocyclic compounds via reaction of metal acetylacetonates with phenylhydrazine, o-phenylenediamine, urea, and thiourea was studied.
MIGRATION TENDENCIES OF FUNCTIONAL GROUPS TOWARD SIGMATROPIC REARRANGEMENT IN 3,3-DISUBSTITUTED 3H-PYRAZOLES

3,3-Disubstituted 3H-pyrazoles la - e aromatise through an intramolecular sigmatropic 1,5-(1,2-)shift of one of the quaternary groups.From a kinetic study of the uncatalysed and of the acid catalysed isomerisation reaction migration tendencies of functional groups in sigmatropic rearrangement toward neutral and toward cationic centers are obtained.
