87865-81-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 87865-81-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,8,6 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 87865-81:
(7*8)+(6*7)+(5*8)+(4*6)+(3*5)+(2*8)+(1*1)=194
194 % 10 = 4
So 87865-81-4 is a valid CAS Registry Number.

, p. 2908 - 2917 (2007/10/03)

We have synthesized the diastereomeric isomers of adenylyl(3′- 5′)adenylyl(3′-5′)adenosine (ApApA), and investigated their helical structures and hybridization properties with d-poly(U) by circular dichroism (CD) and UV melting experiments. The configurat
