927186-58-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 927186-58-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,7,1,8 and 6 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 927186-58:
(8*9)+(7*2)+(6*7)+(5*1)+(4*8)+(3*6)+(2*5)+(1*8)=201
201 % 10 = 1
So 927186-58-1 is a valid CAS Registry Number.

Ribonucleoside analogs with novel hydrogen bonding patterns

-

Page/Page column 12; 13, (2013/03/26)

This invention relates to nucleoside, nucleotide, and oligonucleotide analogs that incorporate non-standard nucleobase analogs, defined to be those that present a pattern of hydrogen bonds to a paired nucleobase analog in a complementary strand that is different from the pattern presented by adenine, guanine, cytosine, and thymine. The invention is specifically concerned with nucleotide analogs that present the donor-donor-acceptor, hydrogen bonding patterns on pyrimidine analogs, and especially those that are analogs of ribonucleotides, including protected ribonucleotides suitable for phosphoramidite-based synthesis of RNA. The heterocycles on these nucleoside analogs are aminopyridones that have electron withdrawing groups attached to the position analogous to the 5-position of the ring in standard pyrimidines, including nitro, cyano, and carboxylic acid derivatives.
