The CAS Registry Mumber 1609198-79-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,9,1,9 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1609198-79:
(9*1)+(8*6)+(7*0)+(6*9)+(5*1)+(4*9)+(3*8)+(2*7)+(1*9)=199
199 % 10 = 9
So 1609198-79-9 is a valid CAS Registry Number.

Synthesis and derivatization of highly-functionalized λ5- phospholes

Ruiz, Javier,Gonzalo, Marta P.,Vivanco, Marilín,García-Granda, Santiago

supporting information, p. 5597 - 5599 (2014/05/20)

A variety of λ5-phosphole derivatives bearing up to three distinct peripheral functionalities have been prepared by regiospecific [3+2] cycloaddition reactions of the diphosphinoketenimine (PPh2) 2CCNtBu (1) with electron-poor alkenes. Selective derivatization of the exocyclic functional groups, including formation of dimetallic complexes with a phosphole core, was subsequently accomplished. the Partner Organisations 2014.
