Check Digit Verification of cas no

The CAS Registry Mumber 1097141-82-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,7,1,4 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1097141-82:
(9*1)+(8*0)+(7*9)+(6*7)+(5*1)+(4*4)+(3*1)+(2*8)+(1*2)=156
156 % 10 = 6
So 1097141-82-6 is a valid CAS Registry Number.

Synthesis of 2,1-benzisoxazoles by nucleophilic substitution of hydrogen in nitroarenes activated by the azole ring

Pokhodylo, Nazariy T.,Teslenko, Yuriy O.,Matiychuk, Vasyl S.,Obushak, Mykola D.

experimental part, p. 2741 - 2748 (2010/02/28)

Reaction of 1-nitro-4-(1,2,3-triazolyl/tetrazolyl)benzenes with arylacetonitriles in an alcoholic medium in the presence of excess alkali gives novel 2,1-benzisoxazoles. These findings indicate a high reactivity of nitroarenes activated by the azole ring due to their electron-deficient character. Moreover, it was found that annulation of the isoxazole ring occurred regioselectively in disubstituted nitroarenes. In the case of 1-(4-nitrophenyl)-1H-tetrazole, the tetrazole ring cleaved faster than the sH-adduct was formed. Georg Thieme Verlag Stuttgart.
