Check Digit Verification of cas no

The CAS Registry Mumber 960299-79-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,6,0,2,9 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 960299-79:
(8*9)+(7*6)+(6*0)+(5*2)+(4*9)+(3*9)+(2*7)+(1*9)=210
210 % 10 = 0
So 960299-79-0 is a valid CAS Registry Number.

2,5-Dihydroxybenzyl and (1,4-dihydroxy-2-naphthyl)methyl, novel reductively armed photocages for the hydroxyl moiety

Kostikov, Alexey P.,Popik, Vladimir V.

, p. 9190 - 9194 (2008/03/14)

(Chemical Equation Presented) Irradiation of alcohols, phenols, and carboxylic acids "caged" with the 2,5-dihydroxybenzyl group or its naphthalene analogue results in the efficient release of the substrate. The initial byproduct of the photoreaction, 4-hydroxyquinone-2-methide, undergoes rapid tautomerization into methyl p-quinone. The UV spectrum of the latter is different from that of the caging chromophore, thus permitting selective irradiation of the starting material in the presence of photochemical products. These photoremovable protecting groups can be armed in situ by the reduction of photochemically inert p-quinone precursors.
