Check Digit Verification of cas no

The CAS Registry Mumber 201156-98-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,1,5 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 201156-98:
(8*2)+(7*0)+(6*1)+(5*1)+(4*5)+(3*6)+(2*9)+(1*8)=91
91 % 10 = 1
So 201156-98-1 is a valid CAS Registry Number.

Nucleophilic aromatic substitution with dialkoxycarbenes

Ross, Joseph P.,Couture, Philippe,Warkentin, John

, p. 1331 - 1335 (1997)

Dimethoxycarbene, generated at 110°C by thermolysis of 2,2-dimethoxy-5,5-dimethyl-Δ3-1,3,4-oxadiazoline, displaces fluoride from aromatic rings that are activated with electron-withdrawing groups. Intermolecular substitution on Sanger's reagent and on hexafluorobenzene are reported, together with intramolecular substitution by a dioxycarbene with a tethered aryl group.
