Check Digit Verification of cas no
The CAS Registry Mumber 500587-45-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,0,5,8 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 500587-45:
(8*5)+(7*0)+(6*0)+(5*5)+(4*8)+(3*7)+(2*4)+(1*5)=131
131 % 10 = 1
So 500587-45-1 is a valid CAS Registry Number.

Efficient regioselective preparation of monobromo and bromoiodo hydroxy pyridines from dibromoderivatives via bromine-lithium exchange

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.
