Check Digit Verification of cas no

The CAS Registry Mumber 52505-65-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,5,0 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 52505-65:
(7*5)+(6*2)+(5*5)+(4*0)+(3*5)+(2*6)+(1*5)=104
104 % 10 = 4
So 52505-65-4 is a valid CAS Registry Number.

Synthesis of novel heterocyclic compounds for antitumor and radioprotective activities

Ghorab,Hassan,Nassar

, p. 447 - 462 (1998)

Some novel pyridothienoxazine (5); pyridothienopyrimidines (6), (8), (9), (14); pyridothienoimidazole (16); isothiazolopyridine (17), and pyridoisothiazolopyrimidines (18-20) were synthesized. The structural assignment of the prepared compounds were based on microanalytical and spectroscopic evidences. Some prepared compounds were tested in vitro for their antitumor and radioprotective activities. Compounds (7), (12), (17) and (19) showed significant activities against EAC cells, at a concentration of 250μg/ml; while the isothiazolopyridine (17) exhibited radioprotective activity.
