Check Digit Verification of cas no
The CAS Registry Mumber 89581-53-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,5,8 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 89581-53:
(7*8)+(6*9)+(5*5)+(4*8)+(3*1)+(2*5)+(1*3)=183
183 % 10 = 3
So 89581-53-3 is a valid CAS Registry Number.

Annular dibromination of hydroxypyridines with NBS in acetonitrile followed by bromine-lithium exchange with RLi and subsequent trapping with H2O or I2 afforded monobromo and bromoiodo derivatives in a completely regioselective way. Iodination of bromo hydroxypyridines with NIS is totally regioselective.
