Check Digit Verification of cas no

The CAS Registry Mumber 132260-01-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,2,6 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 132260-01:
(8*1)+(7*3)+(6*2)+(5*2)+(4*6)+(3*0)+(2*0)+(1*1)=76
76 % 10 = 6
So 132260-01-6 is a valid CAS Registry Number.

An efficient large-scale synthesis of alkyl 5-hydroxy-pyridin- and pyrimidin-2-yl acetate

Morgentin, Rémy,Jung, Frédéric,Lamorlette, Maryannick,Maudet, Micka?l,Ménard, Morgan,Plé, Patrick,Pasquet, Georges,Renaud, Fabrice

experimental part, p. 757 - 764 (2009/04/07)

The synthesis of methyl 2-(5-hydroxy-3-methoxypyridin-2-yl)acetate and alkyl 2-(5-hydroxypyrimidin-2-yl)acetate is described. Methodology for an efficient access to 5-hydroxy-pyridin- and pyrimidin-2-yl acetate cores has been developed. Based on the difference in halogen reactivity, 5-bromo-2-chloropyridine and its pyrimidine analogue were functionalized judiciously by SNAr and palladium-catalyzed reactions. The outlined strategy provides a high-yielding route suitable for large-scale synthesis of these compounds as well as paves the way for a potential rapid access to other heterocyclic analogues.
