Check Digit Verification of cas no

The CAS Registry Mumber 74240-30-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,4 and 0 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74240-30:
(7*7)+(6*4)+(5*2)+(4*4)+(3*0)+(2*3)+(1*0)=105
105 % 10 = 5
So 74240-30-5 is a valid CAS Registry Number.

N-SUBSTITUTED ISONAPHTHALIMIDES. FORMATION AND REACTION WITH AMINES

Ganin, E. V.,Makarov, V. F.,Nikitin, V. I.

, p. 2209 - 2215 (2007/10/02)

N-Substituted isonaphthalimides and N-substituted naphthalimides, as considered previously, are formed in the reaction of 1,8-naphthaloyl chloride with primary amines.The reaction of N-substituted isonaphthalimides with sterically unhindered amines leads to the N,N'-substituted diamides of 1,8-naphthalenedicarboxylic acid.In the case of sterically hindered amines it results in isomerization to the N-substituted naphthalimides.The thermolysis of the N,N'-substituted diamides of 1,8-naphthalenedicarboxylic acid leads to amines and N-substituted naphthalimides.
