Check Digit Verification of cas no

The CAS Registry Mumber 147642-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,6,4 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 147642-83:
(8*1)+(7*4)+(6*7)+(5*6)+(4*4)+(3*2)+(2*8)+(1*3)=149
149 % 10 = 9
So 147642-83-9 is a valid CAS Registry Number.

Synthesis of Acyl Fluorides from Carboxylic Acids Using NaF-Assisted Deoxofluorination with XtalFluor-E

Gonay, Marie,Batisse, Chloé,Paquin, Jean-Fran?ois

, p. 10253 - 10260 (2020/08/12)

The synthesis of acyl fluorides using the deoxofluorination reaction of carboxylic acids using XtalFluor-E is described. This transformation, assisted by a catalytic amount of NaF, occurs at room temperature in EtOAc, where XtalFluor-E behaves as the activating agent and the fluoride source. A wide range of acyl fluorides were obtained in moderate to excellent yields (36-99%) after a simple filtration on a pad of silica gel. We also demonstrated that sequential deoxofluorination/amidation was possible.
