Check Digit Verification of cas no

The CAS Registry Mumber 91540-30-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,5,4 and 0 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 91540-30:
(7*9)+(6*1)+(5*5)+(4*4)+(3*0)+(2*3)+(1*0)=116
116 % 10 = 6
So 91540-30-6 is a valid CAS Registry Number.

The Chemistry of Polycyclic Arene Imine. VI. 1--1a,9b-dihydrophenanthroazirine an Unusual Allylation Product of Phenanthrene 9,10-Imine

Weitzberg, Moshe,Aizenshtat, Zeev,Blum, Jochanan

, p. 865 - 868 (2007/10/02)

Phenanthrene 9,10-imine (1) was shown to react with allyl bromide and 50percent aqueous sodium hydroxide under phase transfer catalysis conditions to give the title compound 3 as the only product.The starting imine 1 is assumed to undergo initially bis alkylation to form an N,N-di-(2-propenyl)phenanthrene 9,10-iminium salt (4) which, in turn, is attacked by a deprotonated phenanthrene imine anion (5).The structure of 3 has been determined by a single crystal X-ray diffraction analysis.

The Chemistry of Polycyclic Arene Imines. V. Reactions of Phenanthrene 9,10-Imine with Nucleophiles under Phase Transfer Conditions

Weitzberg, Moshe,Aizenshtat, Zeev,Blum, Jochanan

, p. 1597 - 1601 (2007/10/02)

Reactions of phenanthrene 9,10-imine (1) with alkyl halides, sodium azide and ammonium thiocyanate in two liquid phase systems were investigated.In the presence of aqueous sodium hydroxide and alkyl halides triethylbenzylammonium (TEBA) salts promote N-al
