Check Digit Verification of cas no

The CAS Registry Mumber 76973-39-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,9,7 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 76973-39:
(7*7)+(6*6)+(5*9)+(4*7)+(3*3)+(2*3)+(1*9)=182
182 % 10 = 2
So 76973-39-2 is a valid CAS Registry Number.

Heterocycles with Potential Heterodienes. III Synthesis and Cycloaddition of 4-Carbomethylen-3-methyl-1-phenyl-5-pyrazolones

Tacconi, G.,Invernizzi, A. Gamba,Righetti, P. P.,Desimoni, G.

, p. 711 - 715 (2007/10/02)

4-Carbomethylen-3-methyl-1-phenyl-5-pyrazolone (4a, 4b) entstehen aus 2-Pyrazoline-4,5-dion 2 und Benzoylmethylen- bzw.Carbomethomethylen-triphenylphosphoranen (3a bzw. 3b) durch Wittig-Synthese. 4a, 4b wurden durch IR- und NMR-Spektren gekennzeichnet.Sie reagieren "in situ" mit Ethylvinylether zu den cis und trans 2,3-Dihydropyran pyrazolen 5a, b bzw. 6a, b.
