Check Digit Verification of cas no

The CAS Registry Mumber 18703-80-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,7,0 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 18703-80:
(7*1)+(6*8)+(5*7)+(4*0)+(3*3)+(2*8)+(1*0)=115
115 % 10 = 5
So 18703-80-5 is a valid CAS Registry Number.

The Generation and Synthetic Utility of Dianions derived from Benzofurancarboxylic Acids

Buttery, Cheryl D.,Knight, David W.,Nott, Andrew P.

, p. 2839 - 2843 (2007/10/02)

The dianionic species, lithium 2-lithiobenzofuran-3-carboxylate (5) and lithium 3-lithiobenzofuran-2-carboxylate (11b) can be readily generated from the parent acids by reaction with lithium diisopropylamide in tetrahydrofuran at low temperatures.While co

METHODS FOR THE HOMOLOGATION OF BENZOFURANCARBOXYLIC ACIDS USING DIANIONIC INTERMEDIATES

Buttery, Cheryl D.,Knight, David W.,Nott, Andrew P.

, p. 4127 - 4130 (2007/10/02)

Dianions (2), (5), and (10), can be derived from the corresponding benzofurancarboxylic acids using lithium diisopropylamide, and are useful intermediates for the homologation of the parent acids.
