Check Digit Verification of cas no

The CAS Registry Mumber 219993-04-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,9,9 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 219993-04:
(8*2)+(7*1)+(6*9)+(5*9)+(4*9)+(3*3)+(2*0)+(1*4)=171
171 % 10 = 1
So 219993-04-1 is a valid CAS Registry Number.

Preparation, characterization and mesomorphic properties of nickel and copper complexes derived from N,N′-bis[3-(3′,4′-dialkoxyphenyl)-3-oxopropenyl] ethylenediamine

Lai, Chung K.,Pang, Yung-Shyen,Tsai, Chun-Hsien

, p. 2605 - 2610 (1998)

The preparation, characterization and mesomorphic properties of copper and nickel complexes derived from N,N′-bis[3-(3′,4′-dialkoxyphenyl)-3-oxopropenyl] ethylenediamine are reported. Liquid crystalline behavior for these structurally similar complexes wa

Synthesis and biological evaluation of 1,4-benzodiazepin-2-ones with antitrypanosomal activity

Spencer, John,Rathnam, Rajendra P.,Harvey, Alan L.,Clements, Carol J.,Clark, Rachel L.,Barrett, Michael P.,Wong, Pui Ee,Male, Louise,Coles, Simon J.,MacKay, Simon P.

, p. 1802 - 1815 (2011/04/17)

A library of 1,4-benzodiazepines has been synthesized and evaluated against Trypanosoma brucei, a causative parasite of Human African trypanosomiasis. Benzodiazepines possessing a P2- transporter motif were found to have MIC values as low as 0.78 μM.
