20890-93-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20890-93-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,9 and 0 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 20890-93:
(7*2)+(6*0)+(5*8)+(4*9)+(3*0)+(2*9)+(1*3)=111
111 % 10 = 1
So 20890-93-1 is a valid CAS Registry Number.

Synthesis of oligopeptides as polynucleotide analogs
Umemiya, Hiroki,Kagechika, Hiroyuki,Hashimoto, Yuichi,Shudo, Koichi
, p. 465 - 475 (2007/10/03)
Several dipeptides which have a uracil moiety in their side chains were designed as nucleotide analogs. Oligopeptides obtained from the dipeptides as monomer units were water-soluble, but exhibited no hypochromic effect with poly A or poly dA.
