Check Digit Verification of cas no

The CAS Registry Mumber 1448855-91-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,8,8,5 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1448855-91:
(9*1)+(8*4)+(7*4)+(6*8)+(5*8)+(4*5)+(3*5)+(2*9)+(1*1)=211
211 % 10 = 1
So 1448855-91-1 is a valid CAS Registry Number.

Toward encoding reactivity using double-stranded DNA. Sequence-dependent native chemical ligation of DNA binding polyamides

Jiménez-Balsa, Adrian,Dodero, Verónica I.,Mascare?as, José L.

, p. 7847 - 7853 (2013/08/23)

The coupling reaction between distamycin-related polyamides equipped with cysteine and thioester groups can be accelerated in the presence of double-stranded (ds) oligonucleotides with selected sequences. While the coupling reaction of reactive partners containing three pyrrole units is accelerated by dsDNAs containing ATTTTA or ATGTTA sites, the heterodimeric coupling between a tripyrrole and a polyamide equipped with two pyrroles and one imidazole, is accelerated by the latter DNA, but not by the other containing the A/T rich tract. These differences can be exploited for selecting preferred coupling pairs from a mixture of reactive monomers; therefore the reaction outcome depends on the instructions provided by the dsDNA sequence.
