637330-23-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 637330-23-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,7,3,3 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 637330-23:
(8*6)+(7*3)+(6*7)+(5*3)+(4*3)+(3*0)+(2*2)+(1*3)=145
145 % 10 = 5
So 637330-23-5 is a valid CAS Registry Number.

Synthesis of fluorophore and quencher monomers for use in Scorpion primers and nucleic acid structural probes

McKeen, Catherine M.,Brown, Lynda J.,Nicol, Jamie T.G.,Mellor, John M.,Brown, Tom

, p. 2267 - 2275 (2003)

The synthesis of monomers to incorporate fluorescein and methyl red within sequence and at the termini of modified oligonucleotides was reported. These monomers were used in the solid-phase synthesis of fluorogenic oligonucleotides for genetic analysis and the study of multi-stranded nucleic acid structures. Fluorescence quenching and energy transfer were also used to study the structural, thermodynamic and kinetic properties of higher order nucleic acid structures.
