Check Digit Verification of cas no
The CAS Registry Mumber 176977-85-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,9,7 and 7 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 176977-85:
(8*1)+(7*7)+(6*6)+(5*9)+(4*7)+(3*7)+(2*8)+(1*5)=208
208 % 10 = 8
So 176977-85-8 is a valid CAS Registry Number.

Improved large-scale preparation of 4-iodopicolinic acid
Lohse, Olivier
, p. 2017 - 2025 (1996)
Dimethylformamide showed a dramatic catalytic effect in the chlorination of picolinic acid with thionyl chloride. Methyl 4-chloropicolinate was directly transformed to 4-iodopicolinic acid in a good yield.
