128563-63-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128563-63-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,6 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 128563-63:
(8*1)+(7*2)+(6*8)+(5*5)+(4*6)+(3*3)+(2*6)+(1*3)=143
143 % 10 = 3
So 128563-63-3 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.
