131261-77-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131261-77-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,2,6 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 131261-77:
(8*1)+(7*3)+(6*1)+(5*2)+(4*6)+(3*1)+(2*7)+(1*7)=93
93 % 10 = 3
So 131261-77-3 is a valid CAS Registry Number.

, p. 6347 - 6350 (2007/10/02)
Nucleotide analogues with a primary amide function attached by a polymethylene chain to C1 of 2-deoxy-D-ribofuranose were synthesized and incorporated into short double helices. The thermodynamic stability of these duplexes was studied. A highe
