Check Digit Verification of cas no

The CAS Registry Mumber 98627-13-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,6,2 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 98627-13:
(7*9)+(6*8)+(5*6)+(4*2)+(3*7)+(2*1)+(1*3)=175
175 % 10 = 5
So 98627-13-5 is a valid CAS Registry Number.

THE REACTIONS OF SOME HALOGENATED PYRIDINES WITH METHOXYDE AND METHANETHIOLATE IONS IN DIMETHYLFORMAMIDE

Testaferri, Lorenzo,Tiecco, Marcello,Tingoli, Marco,Bartoli, Donatella,Massoli, Alberto

, p. 1373 - 1384 (1985)

The reactions of 2,6- and 2,5-dibromopyridines and of 2,3- and 3,5-dichloropyridines with sodium isopropanethiolate and methanethiolate afforded the products of mono- or of bis-substitution depending on the experimental conditions.The same pyridines reacted with sodium methoxide to give good yields of the mono-substituted products; bis-substitution occurred easily only in the case of the 2,6-dibromo- and of the 3,5-dichloropyridine.The syntheses of some methoxy thiomethoxypyridine, starting from the halogeno methoxypyridines or from the halogeno thiomethoxypyridines are also described.The bis-(alkylthio)pyridines can be fragmented by sodium in HMPA to give the bis(mercapto)pyridines.
