78443-29-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 78443-29-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,4,4 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 78443-29:
(7*7)+(6*8)+(5*4)+(4*4)+(3*3)+(2*2)+(1*9)=155
155 % 10 = 5
So 78443-29-5 is a valid CAS Registry Number.

STABLE 2H-PYRAN DERIVATIVES ACCESSIBLE BY CYCLOCONDENSATION OF p-SUBSTITUTED BENZOYLACETONITRILES

Kuthan, Josef,Palecek, Jaroslav,Valihrach, Jiri

, p. 748 - 758 (2007/10/02)

The 2H-pyrans IIa-f can be prepared by thermal cyclocondensation of the ketonitriles Ia-f.The alternative structure III of the compounds obtained has been excluded unambiguously on the basis of spectral data.The compounds VII to XI have been isolated as byproducts of the said cyclocondensation of the compound Ia in acetic acid with catalysis of ammonium acetate.Probable course of the reaction investigated is discussed.
