Check Digit Verification of cas no

The CAS Registry Mumber 500699-23-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,0,6,9 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 500699-23:
(8*5)+(7*0)+(6*0)+(5*6)+(4*9)+(3*9)+(2*2)+(1*3)=140
140 % 10 = 0
So 500699-23-0 is a valid CAS Registry Number.

Hydride-donor abilities of 1,4-dihydropyridines: A comparison with π nucleophiles and borohydride anions

Richter, Dorothea,Mayr, Herbert

, p. 1958 - 1961 (2009)

(Chemical Equation Presented) How are dihydropyridines like indoles? Both groups of compounds have similar nucleophilicity parameters N and are therefore suitable substrates for iminium-catalyzed reactions of α,β- unsaturated aldehydes. The N parameters of 1,4-dihydropyridines were derived from the rates of hydride transfer reactions to benzhydrylium ions (see scheme).
