Check Digit Verification of cas no

The CAS Registry Mumber 316808-04-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,6,8,0 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 316808-04:
(8*3)+(7*1)+(6*6)+(5*8)+(4*0)+(3*8)+(2*0)+(1*4)=135
135 % 10 = 5
So 316808-04-5 is a valid CAS Registry Number.

A second-generation copper(II)-mediated metallo-DNA-base pair

Zimmermann, Nicole,Meggers, Eric,Schultz, Peter G.

, p. 13 - 25 (2007/10/03)

Metal-dependent pairing of nucleobases represents an alternative DNA base pairing scheme. Our first-generation copper(II)-mediated pyridine-2,6- dicarboxylate (Dipic) and pyridine (Py) metallo-base pair has a stability comparable to the natural base pairs dA:dT and dC:dG but does not have the selectivity of the Watson Crick base pairs. In order to increase the selectivity of base pair formation, a second-generation metallo-base pair was generated consisting of a pyridine-2,6-dicarboxamide (Dipam) and a pyridine (Py) nucleobase. This new metallo-base pair is more stable than the natural base pairs dA:dT and dC:dG and highly selective against mispairing. In addition, incorporation of multiple metallo-base pairs into DNA results in the formation of stable duplexes demonstrating that hydrogen bonding base pairs can efficiently be replaced by metal-dependent base pairs at multiple sites in DNA.
