Check Digit Verification of cas no

The CAS Registry Mumber 1415387-18-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,5,3,8 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1415387-18:
(9*1)+(8*4)+(7*1)+(6*5)+(5*3)+(4*8)+(3*7)+(2*1)+(1*8)=156
156 % 10 = 6
So 1415387-18-6 is a valid CAS Registry Number.

Synthesis of novel pyrazolo[3,4-d]pyrimidine derivatives as potential anti-breast cancer agents

Abd El Hamid, Mohammed K.,Mihovilovic, Marko D.,El-Nassan, Hala B.

, p. 323 - 328 (2013/01/15)

A series of new 1-aryl-4-benzylidenehydrazinyl-3-methylsulphanyl- pyrazolo[3,4-d]pyrimidines 6a-p was synthesized. The cytotoxic activity of the newly synthesized compounds against human breast cancer cell line, MCF7 was investigated. Most of the test compounds showed potent antitumor activity comparable to that of doxorubicin. The 1-phenyl series (6a-i) exhibited better antitumor activity than 1-(4-methoxyphenyl) series (6j-p). 4-[2-(4- Fluorobenzylidene)hydrazinyl]-3-(methylsulphanyl)-1-phenyl-1H-pyrazolo[3,4-d] pyrimidine (6d) was the most active compound in this study with IC50 equal to 7.5 nM.
