Check Digit Verification of cas no

The CAS Registry Mumber 119415-01-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,4,1 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 119415-01:
(8*1)+(7*1)+(6*9)+(5*4)+(4*1)+(3*5)+(2*0)+(1*1)=109
109 % 10 = 9
So 119415-01-9 is a valid CAS Registry Number.

On the Tautomerism of 2-Phenacyl-4-pyrimidinones and Related Compounds

Elguero, Jose,Goya, Pilar,Martinez, Ana,Rozas, Isabel

, p. 919 - 924 (2007/10/02)

3-Methyl-2-phenacyl-4-pyrimidinones 1, 2 have been synthesized using the sulfide contraction.According to the NMR data, the compounds 1, 2 exist exclusively as the benzoylmethylene tautomers a both in solution and in the solid state.AM1 calculations of the parent system are in agreement with the experimental observations.The study of the tautomeric equilibrium by this semiempirical method has been extended to other cases of enaminoketone/enolimine tautomerism. - Key Words: Pyrimidinones / Tautomerism / AM1 calculations
