Check Digit Verification of cas no

The CAS Registry Mumber 2647-49-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,4 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2647-49:
(6*2)+(5*6)+(4*4)+(3*7)+(2*4)+(1*9)=96
96 % 10 = 6
So 2647-49-6 is a valid CAS Registry Number.

Synthesis and spectral properties of 2-[(o- and p-substituted)aminophenyl]-3H-5-[(o- and p-substituted)phenyl]-7-chloro-1,4-benzodiazepines

Cortes Cortes,Salazar Franco,Garcia Mellado

, p. 663 - 669 (2007/10/03)

A series of twelve new 2-[(o- and p-substituted)aminophenyl]-3H-5-[(o- and p-substituted)phenyl]-7-chloro-1,4-benzodiazepines, which have possible pharmacological properties has been obtained. The synthesis was carried out following six steps. The structure of all products was corroborated by ir, 1H nmr, 13C nmr and ms. In addition for the compound 2-(o-chloroaminophenyl)-3H-5-(o-fluorophenyl)-7-chloro-1,4-benzodiazepine 7, its structure was confirmed by X-ray diffraction.
