Check Digit Verification of cas no

The CAS Registry Mumber 14789-44-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,7,8 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 14789-44:
(7*1)+(6*4)+(5*7)+(4*8)+(3*9)+(2*4)+(1*4)=137
137 % 10 = 7
So 14789-44-7 is a valid CAS Registry Number.

The Photochemical Reactions of 9,10-Anthracenedicarbonitrile and 1,4-Naphthalenedicarbonitrile in Acetonitrile in the Presence of Bases

Freccero, Mauro,Mella, Mariella,Albini, Angelo

, p. 2115 - 2130 (2007/10/02)

Irradiation of 9,10-anthracenedicarbonitrile (DCA) in MeCN-MeOH or MeCN-H2O containing hydroxides or methoxides leads to 9-methylimino-10-anthracenecarbonitrile (isolated, but easily hydrolyzed to the corresponding amine).Minor products are polycyanated amines and 9-hydroxy-10-anthracenecarbonitrile.Irradiation in neat MeOH causes decyanation.In both cases the first step is reduction to DCA-*, which persists for hour under these conditions.Evidence for the mechanism leading from the radical anion to the observed products is supplied.The key steps are protonation to yield the radical DCAH* and addition of the latter to acetonitrile, or to better nucleophiles when these are present. 1,4-Naphthalenedicarbonitrile is similarly transformed to the 4-amino-1-carbonitrile.
