Check Digit Verification of cas no

The CAS Registry Mumber 1620164-51-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,1,6 and 4 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1620164-51:
(9*1)+(8*6)+(7*2)+(6*0)+(5*1)+(4*6)+(3*4)+(2*5)+(1*1)=123
123 % 10 = 3
So 1620164-51-3 is a valid CAS Registry Number.

Synthesis and antiproliferative activity of aromatic and aliphatic bis[aminomethylidene(bisphosphonic)] acids

Goldeman, Waldemar,Nasulewicz-Goldeman, Anna

, p. 3475 - 3479 (2014)

A series of aromatic and aliphatic bis[aminomethylidene(bisphosphonic)] acids was synthesized in the reaction of triethylphosphite with isonitriles followed by hydrolysis or dealkylation. The in vitro anti-proliferative effect of all synthesized tetraphosphonic acids against MCF-7 breast cancer cells, J774E macrophages and HL-60 promyelocytic leukemia cells was determined. Three aromatic derivatives (5a, 5f and 5j) showed a similar or higher anti-proliferative activity than zoledronic acid.
