Check Digit Verification of cas no

The CAS Registry Mumber 108656-50-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,6,5 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 108656-50:
(8*1)+(7*0)+(6*8)+(5*6)+(4*5)+(3*6)+(2*5)+(1*0)=134
134 % 10 = 4
So 108656-50-4 is a valid CAS Registry Number.

Preparation of 3,4-Fused Cyclopropabenzenes and Cyclopropabenzenyl Cations

Mueller, Paul,Rodriguez, Domingo

, p. 1546 - 1553 (1986)

A series of 3,4-disubstituted (4a,b) or 3,4-fused (4c-e) 1,1-di-fluorocyclopropabenzenes, including the very strained 1,1-difluoro-3,4-dihydro-1H-cyclobutacyclopropabenzene (4e) have been synthesized and characterized.Dissolution of these difluoro derivatives in fluorosulfonic acid affords the fluoro cations 3a-e. 1H-, 19F-, and 13C-NMR data of the cations are reported and discussed with respect to those of the precursors.
