Check Digit Verification of cas no

The CAS Registry Mumber 205500-32-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,5,0 and 0 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 205500-32:
(8*2)+(7*0)+(6*5)+(5*5)+(4*0)+(3*0)+(2*3)+(1*2)=79
79 % 10 = 9
So 205500-32-9 is a valid CAS Registry Number.

2'-Deoxy-2'(S)-ethinyl oligonucleotides: A modification which selectively stabilizes oligoadenylate pairing to DNA complements

Buff, Rolf,Hunziker, Juerg

, p. 521 - 524 (1998)

Oligonucleotides consisting of 2'-deoxy-2'(S)-ethinyl-thymidine, -uridine, and -adenosine have been prepared. Whereas the modified pyrimidine oligonucleotides uniformly lead to weaker pairing affinity with DNA and RNA complements, the corresponding adenine oligonucleotides show enhanced thermal stability in duplexes with complementary DNA and decreased stability with RNA.
