Check Digit Verification of cas no

The CAS Registry Mumber 59699-53-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,6,9 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 59699-53:
(7*5)+(6*9)+(5*6)+(4*9)+(3*9)+(2*5)+(1*3)=195
195 % 10 = 5
So 59699-53-5 is a valid CAS Registry Number.

Novel applications of hypervalent iodine: PIFA mediated synthesis of benzo[c]phenanthiridines and benzo[c]phenanthridinones

Moreno,Tellitu,Etayo,SanMartín,Domínguez

, p. 5403 - 5411 (2007/10/03)

A short and efficient access to benzo[c]phenanthridines and phenanthridinones is achieved by the action of phenyliodine(III)-bis(trifluoroacetate) (PIFA) on properly substituted benzylnaphthylamines and naphthylbenzamides, respectively. This reagent promotes a non-phenolic oxidative biaryl coupling process, the key step of the synthesis. A study of the electronic and steric requirements of the substrates is carried out since, in some cases, dimerization processes prevail over intramolecular cyclization. A mechanistic proposal is also included.
