Check Digit Verification of cas no

The CAS Registry Mumber 718646-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,1,8,6,4 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 718646-40:
(8*7)+(7*1)+(6*8)+(5*6)+(4*4)+(3*6)+(2*4)+(1*0)=183
183 % 10 = 3
So 718646-40-3 is a valid CAS Registry Number.

Synthesis of substituted 4,5,8,7-tetrafluorobenzo[d]-λ5- phospholes

Trishin,Namestnikov,Bel'skii

, p. 189 - 192 (2004)

The reactions of diethyl pentafluorophenylphosphonite and ethyl bis(pentafluorophenyl)phosphinite with activated alkynes proceed as two-stage cycloaddition processes and lead to formation of sufficiently stable heterocyclic fused fluorophosphoranes. Hydro
