678186-83-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 678186-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,8,1,8 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 678186-83:
(8*6)+(7*7)+(6*8)+(5*1)+(4*8)+(3*6)+(2*8)+(1*3)=219
219 % 10 = 9
So 678186-83-9 is a valid CAS Registry Number.

Olefinic peptide nucleic acid (OPA)
Gautschi, Daniel,Leumann, Christian J.
, p. 1211 - 1213 (2007/10/03)
The olefinic peptide nucleic acid analogues (OPA) monomers containing the bases thymine and adenine were synthesised in 11 steps. Fully modified oligomers containing these units were prepared and their pairing properties assessed by means of UV-melting ex
