Check Digit Verification of cas no

The CAS Registry Mumber 164391-19-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,4,3,9 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 164391-19:
(8*1)+(7*6)+(6*4)+(5*3)+(4*9)+(3*1)+(2*1)+(1*9)=139
139 % 10 = 9
So 164391-19-9 is a valid CAS Registry Number.

NOVEL HYDROPHILIC DERIVATIVES OF 2-ARYL-4-QUINOLONES AS ANTICANCER AGENTS

-

Page/Page column 26-28, (2008/12/06)

2-aryl-4-quinolones are converted into phosphates by reacting with tetrabenzyl pyrophosphate to form dibenzyl phosphates thereof, which are then subject to hydrogenation to replace dibenzyl groups with H, followed by reacting with Amberlite IR-120(Na+ form) to form disodium salts. The results of preliminary screening revealed that these phosphates showed significant anti-cancer activity. A novel intermediate, 2-selenophene 4-quinolone and Λ/, Λ/-dialkylaminoalkyl derivatives of 2-phenyl-4-quinolones are also synthesized. These novel intermediates exhibited significant anticancer activities.
