Check Digit Verification of cas no

The CAS Registry Mumber 1351858-27-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,1,8,5 and 8 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1351858-27:
(9*1)+(8*3)+(7*5)+(6*1)+(5*8)+(4*5)+(3*8)+(2*2)+(1*7)=169
169 % 10 = 9
So 1351858-27-9 is a valid CAS Registry Number.

Synthesis and evaluation of anti-proliferative activity of 1,4-disubstituted phthalazines

Abouzid, Khaled A. M.,Khalil, Nadia A.,Ahmed, Eman M.

, p. 3288 - 3293,6 (2020/08/20)

A series of new phthalazine derivatives 3a-i and 4a-c were synthesized via the reaction of 1-chlorophthalazine derivative 2 with either N-substituted-piperazines, primary or their secondary amines. The structure of the synthesized, new compounds were characterized by spectral data. The anti-proliferative activity on human breast cancer cell line MCF-7 of the synthesized compounds was determined. The results showed that six of the test compounds (3a, 3g, 3i, and 4a-c) displayed potent cytotoxic activity ranging from 1.4 to 2.3 μmol.
