Check Digit Verification of cas no

The CAS Registry Mumber 1256379-85-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,3,7 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1256379-85:
(9*1)+(8*2)+(7*5)+(6*6)+(5*3)+(4*7)+(3*9)+(2*8)+(1*5)=187
187 % 10 = 7
So 1256379-85-7 is a valid CAS Registry Number.

Transfer of Sequence Information and Replication of Diimine Duplexes

Strom, Kyle R.,Szostak, Jack W.,Prywes, Noam

, p. 3754 - 3761 (2019)

The ability of the biopolymers RNA and DNA to store and transfer information is essential to life. Herein, we demonstrate template-directed replication in a set of dimer duplexes that use reversible covalent bonds to form base-pairing interactions. Binary sequence information was encoded as a sequence of aniline and benzaldehyde subunits linked together by a diethynyl benzene backbone. These dimers formed sequence-specific, imine-linked duplexes, which could be separated and used as templates for the synthesis of daughter duplexes with identical sequences.
