Check Digit Verification of cas no

The CAS Registry Mumber 199997-97-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,9,9 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 199997-97:
(8*1)+(7*9)+(6*9)+(5*9)+(4*9)+(3*7)+(2*9)+(1*7)=252
252 % 10 = 2
So 199997-97-2 is a valid CAS Registry Number.

Synthesis of diverse ethoxyformacetal oligomers. Toward libraries of metal-coordinating unnatural biopolymers

Hall, Dennis G.,Schultz, Peter G.

, p. 7825 - 7828 (1997)

An expedient two-step iterative protocol for the solution-phase elaboration of ethoxyformacetal oligomers is described. A set of four O,S- thioformacetal donor monomers, with diverse chiral side-chains, were coupled using NIS/TfOH activation to afford three model tetramers.
