Check Digit Verification of cas no

The CAS Registry Mumber 155222-80-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,2,2 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 155222-80:
(8*1)+(7*5)+(6*5)+(5*2)+(4*2)+(3*2)+(2*8)+(1*0)=113
113 % 10 = 3
So 155222-80-3 is a valid CAS Registry Number.

A Study of the Ferrous Ion-initiated SRN1 Reactions of Halogenoarenes with tert-Butyl Acetate and N-Acylmorpholine Enolates

Leeuwen, Milko van,McKillop, Alexander

, p. 2433 - 2440 (2007/10/02)

A detailed preparative study is reported of the ferrous ion-initiated SRN1 reactions of a range of halogenoarenes with the sodium enolates of tert-butyl acetate, n-acetylmorpholine and a number of higher N-acylmorpholines.Smooth and rapid substitution occurs in many cases, and good to excellent yields were obtained of arylacetic esters or acids, arylacetamides and arylalkanamides.The broad scope and limitations of the process have been defined, and the possible role of the ferrous ion is discussed.
