Check Digit Verification of cas no

The CAS Registry Mumber 185798-88-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,7,9 and 8 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 185798-88:
(8*1)+(7*8)+(6*5)+(5*7)+(4*9)+(3*8)+(2*8)+(1*8)=213
213 % 10 = 3
So 185798-88-3 is a valid CAS Registry Number.

Unconventional acceptor and donor functional groups linked by a captodative spacer

Alcalde, Ermitas,Gisbert, Maria,Pons, Josep M.,Perez-Garcia, Lluisa

, p. 15197 - 15208 (1996)

The chemical stability to oxidation of a set of compounds built up from acceptor and donor subunits linked by a methylene or a hydroxymethylene group was studied. Whereas 1-butyl-3-[1,2,4-triazol-5(3)-ylmethyl]pyridinium salts 2d,e showed high stability to oxidation, 1-butyl-4-[imidazol-4(5)-ylhidroxymethyl]pyridinium salt 14f was oxidised spontaneously to the corresponding carbonyl compound, indicating the capability of the oxidation phenomenon to be controlled by the nature of the building blocks.
