Check Digit Verification of cas no

The CAS Registry Mumber 643013-63-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,3,0,1 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 643013-63:
(8*6)+(7*4)+(6*3)+(5*0)+(4*1)+(3*3)+(2*6)+(1*3)=122
122 % 10 = 2
So 643013-63-2 is a valid CAS Registry Number.

New building blocks for the assembly of sequence selective molecular zippers.

Hunter, Christopher A,Jones, Philip S,Tiger, Pascale M N,Tomas, Salvador

, p. 1642 - 1643 (2003)

Synthetic H-bonded molecular zippers contain no sequence information that can be used to engineer the selective binding interactions characteristic of biopolymers; reversing the sense of the amide bonds in the two binding partners generates a new orthogonal recognition motif and the mutually complementary binding partners form complexes an order of magnitude more stable than the corresponding mismatch complexes.
