Check Digit Verification of cas no

The CAS Registry Mumber 100703-93-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,7,0 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 100703-93:
(8*1)+(7*0)+(6*0)+(5*7)+(4*0)+(3*3)+(2*9)+(1*3)=73
73 % 10 = 3
So 100703-93-3 is a valid CAS Registry Number.

Three-step regioselective synthesis of 2,3-difluorohalobenzenes using tetrafluoroethylene and buta-1,3-diene as starting building blocks

Egorov, M. P.,Lipkind, M. B.,Nefedov, O. M.,Volchkov, N. V.

, p. 925 - 932 (2021)

The gas-phase copyrolysis of tetrafluoroethylene and buta-1,3-diene in a flow tube reactor at 490–510 °C gives 3,3,4,4-tetrafluorocyclohex-1-ene, which is selectively converted to 1-bromo- or 1-chloro-2,3-difluorobenzene via intermediate steps of halogenation and dehydrohalogenation.
