Check Digit Verification of cas no

The CAS Registry Mumber 129431-03-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,4,3 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 129431-03:
(8*1)+(7*2)+(6*9)+(5*4)+(4*3)+(3*1)+(2*0)+(1*3)=114
114 % 10 = 4
So 129431-03-4 is a valid CAS Registry Number.

Synthesis and DNA-binding ability of C2R-fluoro substituted DC-81 and its dimers

Kamal, Ahmed,Rajasekhar Reddy,Murali Mohan Reddy

, p. 803 - 806 (2007/10/03)

C2R-Fluoro substituted DC-81 and its dimers have been synthesized that exhibit significant DNA-binding ability, particularly the five carbon alkane spacer compound (6c) showed the helix melting temperature (ΔTm) of 18.8 °C after incubation of 36 h at 37 °C.

Efficient "One-Pot" Synthesis of N-Trityl Amino Acids

Barlos, Kleomenis,Papaioannou, Dionysios,Theodoropoulos, Dimitrios

, p. 1324 - 1326 (2007/10/02)

A sequential procedure has been developed whereby neutral amino acids 1 were tritylated via their corresponding trimethylsilyl esters 2 to afford, after mild hydrolysis, N-trityl amino acids 3 in high yields and purity.Hydroxy amino acids 4 were preferent
