Check Digit Verification of cas no

The CAS Registry Mumber 198879-82-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,8,7 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 198879-82:
(8*1)+(7*9)+(6*8)+(5*8)+(4*7)+(3*9)+(2*8)+(1*2)=232
232 % 10 = 2
So 198879-82-2 is a valid CAS Registry Number.

Direct electrophilic monofluoromethylation

Prakash, G. K. Surya,Ledneczki, Istvan,Chacko, Sujith,Olah, George A.

, p. 557 - 560 (2008)

Monofluoromethyl derivatives of various nucleophiles have been synthesized using a new electrophilic monofluoromethylating reagent developed. The S-(monofluoromethyl)diarylsulfonium tetrafluoroborate has been shown to be effective for the introduction of an electrophilic monofluoromethyl group into C, S, O, N, and P nucleophiles. This methodology has been expanded for the synthesis of various biologically important compounds.
