Check Digit Verification of cas no

The CAS Registry Mumber 152565-99-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,5,6 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 152565-99:
(8*1)+(7*5)+(6*2)+(5*5)+(4*6)+(3*5)+(2*9)+(1*9)=146
146 % 10 = 6
So 152565-99-6 is a valid CAS Registry Number.

Synthesis of 1-Azabicyclonona-3,6-diene Derivatives by a Modified Prins Reaction

Csuzdi, Emese,Ling, Istvan,Abraham, Gizella,Pallagi, Istvan,Solyom, Sandor

, p. 347 - 354 (2007/10/02)

Intramolecular electrophilic cyclization reactions were performed with 1-(3-oxo-3-phenylpropyl)-1,2,5,6-tetrahydropyridine derivatives 1a-p in strong acids to give 4,6-diphenyl-substituted 1-azabicyclononadienes 2a-p.Some qualitative observations were made on substituents and reaction conditions influencing the ring closure reaction.Naphthyl-substituted starting compounds 3a, b were converted into pentacyclic compounds 4a, b which represent a new ring system, suggesting the occurrence of a carbenium ion intermediate in the ring closure reaction.Some of the compounds 2a-p show remarkable antifungal and antibacterial effects. - Key Words: Prins reactions / Carbenium ions / 1-Azabicyclononadienes / Isogranatanines / Antifungal agents / Antibacterial agents
