The CAS Registry Mumber 1312213-22-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,2,2,1 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1312213-22:
(9*1)+(8*3)+(7*1)+(6*2)+(5*2)+(4*1)+(3*3)+(2*2)+(1*2)=81
81 % 10 = 1
So 1312213-22-1 is a valid CAS Registry Number.

3-haloquinolines by Friedlaender reaction of α-haloketones

Ryabukhin, Sergey V.,Naumchik, Vasiliy S.,Plaskon, Andrey S.,Grygorenko, Oleksandr O.,Tolmachev, Andrey A.

experimental part, p. 5774 - 5781 (2011/09/12)

A general approach to 3-fluoro-, 3-chloro-, and 3-bromoquinolines which relies on organosilane-promoted Friedlaender reaction of α-haloketones is described. The scope of the methylene component as well as influence of the organosilane component on the outcome of the reaction is studied. The method can be used under parallel synthesis conditions.
