647852-33-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 647852-33-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,7,8,5 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 647852-33:
(8*6)+(7*4)+(6*7)+(5*8)+(4*5)+(3*2)+(2*3)+(1*3)=193
193 % 10 = 3
So 647852-33-3 is a valid CAS Registry Number.

Intrastrand locks increase duplex stability and base pairing selectivity
Prestinari, Cora,Richert, Clemens
, p. 10824 - 10826 (2011/11/05)
Oligodeoxynucleotide probes with disulfide locks between neighboring nucleobases show increases in melting point for duplexes with RNA target strands of up to 7.6 °C. The weakly pairing TT dimers are replaced with locked 2′-deoxy-5-(thioalkynyl)uridine re
