Check Digit Verification of cas no
The CAS Registry Mumber 173278-51-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,2,7 and 8 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 173278-51:
(8*1)+(7*7)+(6*3)+(5*2)+(4*7)+(3*8)+(2*5)+(1*1)=148
148 % 10 = 8
So 173278-51-8 is a valid CAS Registry Number.

First synthesis of 3-mercapto-2(1H)-pyridinone, a simple disubstituted pyridine useful for synthesis of the 4-azaphenoxathiine ring system and its novel diazaphenoxathiine analogs: 1,6-Diazaphenoxathiine and 2,6-diazaphenoxathiine

3-Mercapto-2(1H)-pyridinone (1) can be synthesized in three simple high-yielding steps from readily available 2-tert-butylthiazolo[4,5-b]pyridine (2). Its disodium salt condenses with o-chloronitrobenzene, 2-chloro-3-nitropyridine, and 3-chloro-4-nitropyridine 1-oxide to give respectively 4-azaphenoxathiine (10), 1,6-diazaphenoxathiine (12), and 2,6-diazaphenoxathiine 2-oxide (14) which reduces to 2,6-diazaphenoxathiine (15). The structures of these previously unreported azaphenoxathiine systems were confirmed by assignment of their respective 13C NMR spectra.
