Check Digit Verification of cas no
The CAS Registry Mumber 169888-58-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,8,8 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 169888-58:
(8*1)+(7*6)+(6*9)+(5*8)+(4*8)+(3*8)+(2*5)+(1*8)=218
218 % 10 = 8
So 169888-58-8 is a valid CAS Registry Number.

Synthesis of 1,2,3-Triazolopyridine Ester Derivatives
Latham, Elliot J.,Stanforth, Stephen P.
, p. 787 - 790 (2007/10/03)
Lithiation of 1,2,3-triazolopyridines 4b and 4c with lithium diisopropylamide (LDA) gave the corresponding lithio derivatives 5b and 5c from which esters 6b and 6c were obtained by treatment with carbon dioxide and then dimethyl sulfate.Lithio derivatives 5a-5c reacted with DMF giving aldehydes 7a-7c.Esters 9a-9c were prepared from aldehydes 7a-7c and carbomethoxymethylenetriphenylphosphorane.
