Check Digit Verification of cas no

The CAS Registry Mumber 1612222-92-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,2,2,2 and 2 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1612222-92:
(9*1)+(8*6)+(7*1)+(6*2)+(5*2)+(4*2)+(3*2)+(2*9)+(1*2)=120
120 % 10 = 0
So 1612222-92-0 is a valid CAS Registry Number.

Expedient synthesis of α-(2-azaheteroaryl) acetates via the addition of silyl ketene acetals to azine- N -oxides

Londregan, Allyn T.,Burford, Kristen,Conn, Edward L.,Hesp, Kevin D.

, p. 3336 - 3339 (2014/07/08)

A new and expedient synthesis of α-(2-azaheteroaryl) acetates is presented. The reaction proceeds rapidly under mild conditions via the addition of silyl ketene acetals to azine-N-oxides in the presence of the phosphonium salt PyBroP. This procedure affords diverse α-(2-azaheteroaryl) acetates which are highly desirable components/building blocks in molecules of pharmaceutical interest but are traditionally challenging to synthesize via contemporary methods. The reaction optimization and mechanism as well as a novel electronically enhanced PyBroP derivative are described.
