Check Digit Verification of cas no

The CAS Registry Mumber 1609955-67-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,9,9,5 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1609955-67:
(9*1)+(8*6)+(7*0)+(6*9)+(5*9)+(4*5)+(3*5)+(2*6)+(1*7)=210
210 % 10 = 0
So 1609955-67-0 is a valid CAS Registry Number.

Synthesis and gene transfection activity of cyclen-based cationic lipids with asymmetric acyl-cholesteryl hydrophobic tails

Liu, Bao-Quan,Yi, Wen-Jing,Zhang, Ji,Liu, Qiang,Liu, Yan-Hong,Fan, Sheng-Di,Yu, Xiao-Qi

, p. 3484 - 3492 (2014/05/20)

A series of novel 1,4,7,10-tetraazacyclododecane (cyclen)-based cationic lipids with asymmetric double hydrophobic tails (cholesteryl and long aliphatic chains) were designed and synthesized. Lysine was chosen as a linking moiety in the molecular backbone. The liposomes formed from 8 and dioleoylphosphatidylethanolamine (DOPE) could bind and condense plasmid DNA into nanoparticles under a low N/P ratio. These nano-scaled lipoplexes have low cytotoxicity, and might efficiently transfect A549 cells. In vitro transfection results revealed that all cationic lipids showed a comparable or better transfection efficiency (TE) than commercially available Lipofectamine 2000. The length and saturation degree of the aliphatic chain would affect their gene transfection performance, and the linoleic acid-containing 8e could give the best TE. the Partner Organisations 2014.
