Check Digit Verification of cas no

The CAS Registry Mumber 98014-28-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,0,1 and 4 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 98014-28:
(7*9)+(6*8)+(5*0)+(4*1)+(3*4)+(2*2)+(1*8)=139
139 % 10 = 9
So 98014-28-9 is a valid CAS Registry Number.

Synthesis and comparison of N-fluorobis[(perfluoroalkyl)sulfonyl]imides with different perfluoroalkyl groups

Zhang, Jie,Desmarteau, Darryl D.

, p. 253 - 257 (2007/10/03)

N-fluorobis[(perfluoroalkyl)sulfonyl]imides, CF3SO2N(F)SO2Rf (Rf′=C4F9, C6F13, C8F17) and (C4F9SO2)2NF, were prepared by direct fluorination of corresponding N-H compounds using elemental fluorine without a solvent in good to excellent yields. All of these N-F compounds are electrophilic fluorination agents and can easily deliver F+ to certain molecules. Their reactions with aromatic rings, beta-diketones, and alkenes were investigated to compare their fluorination power.
