Check Digit Verification of cas no
The CAS Registry Mumber 210169-13-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,0,1,6 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 210169-13:
(8*2)+(7*1)+(6*0)+(5*1)+(4*6)+(3*9)+(2*1)+(1*3)=84
84 % 10 = 4
So 210169-13-4 is a valid CAS Registry Number.

2,4,6-Tribromo-3,5-difluoro-pyridine 1 was used as the starting material for the synthesis of a variety of multifunctional pyridine derivatives. For example, nucleophilic substitution reactions involving appropriate difunctional nucleophiles gave products resulting from intramolecular cyclisation processes and the organolithium derivative 9, readily prepared from 1, could be trapped by various of electrophilic reagents.
