Check Digit Verification of cas no

The CAS Registry Mumber 77444-55-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,4,4 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 77444-55:
(7*7)+(6*7)+(5*4)+(4*4)+(3*4)+(2*5)+(1*5)=154
154 % 10 = 4
So 77444-55-4 is a valid CAS Registry Number.

Efficient, "tin-free" radical cyclization to aromatic systems. Synthesis of 5,6,8,9,10,11-hexahydroindolo[2,1-a]isoquinolines

Menes-Arzate, Martha,Martínez, Roberto,Cruz-Almanza, Raymundo,Muchowski, Joseph M.,Osornio, Yazmin M.,Miranda, Luis D.

, p. 4001 - 4004 (2004)

Efficient radical cyclization of alkyl iodides to various aromatic systems including pyrrole, indole, isoquinolone, pyridone, and benzene, mediated by dicumyl peroxide, is described. The methodology was used to provide access to 5,6,8,9,10,11-hexahydroindolo[2,1-a]isoquinoline derivatives.

Radical cyclizations to quinolone and isoquinolone systems under oxidative and reductive conditions

Osornio, Yazmin M.,Miranda, Luis D.,Cruz-Almanza, Raymundo,Muchowski, Joseph M.

, p. 2855 - 2858 (2007/10/03)

Radical cyclizations to quinolone and isoquinolone systems under Fenton-type and n-Bu3SnH-mediated conditions are described. For N-iodoalkylquinolones, ca. 3:1 mixtures of oxidative cyclization products at C-2, and unexpectedly at C-8, were obtained under both conditions. Five- or six-membered oxidative cyclization products were obtained from N-iodoalkylisoquinolones under Fenton-type conditions, whereas n-Bu 3SnH-mediated reactions gave products of reductive cyclization in the five, six, and seven-membered series.
