Check Digit Verification of cas no
The CAS Registry Mumber 21418-21-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,4,1 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 21418-21:
(7*2)+(6*1)+(5*4)+(4*1)+(3*8)+(2*2)+(1*1)=73
73 % 10 = 3
So 21418-21-3 is a valid CAS Registry Number.

A highly regioselective reaction of N-fluoropyridinium salts with stabilized sulfur, oxygen, and nitrogen nucleophiles: A convenient route to 2-substituted pyridines
Kiselyov,Strekowski
, p. 1361 - 1364 (2007/10/02)
2-Substituted pyridines are efficiently obtained by the reactions of N- fluoropyridinium tetrafluoroborate or triflate with anions derived from benzenethiols, phenols, azoles, cyanamide, and with azide anion. The results are consistent with a nucleophile addition at the position 2 of the N- fluoropyridinium cation as the major reaction pathway.
