Check Digit Verification of cas no

The CAS Registry Mumber 428855-22-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,8,8,5 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 428855-22:
(8*4)+(7*2)+(6*8)+(5*8)+(4*5)+(3*5)+(2*2)+(1*2)=175
175 % 10 = 5
So 428855-22-5 is a valid CAS Registry Number.

A new synthetic method for α-alkoxycarbonyl iminium salt and its reaction with nucleophiles

Shimizu, Makoto,Itou, Hiroyuki,Miura, Megumi

, p. 3296 - 3297 (2005)

An iminium salt was easily prepared using the oxidation of amino ketene silyl acetal with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone, and the subsequent nucleophilic addition to this iminium species proceeded efficiently to afford α-amino esters in good yields. Copyright

Conjugated imines and iminium salts as versatile acceptors of nucleophiles

Shimizu, Makoto,Hachiya, Iwao,Mizota, Isao

scheme or table, p. 874 - 889 (2009/07/10)

Growing interests in nitrogen-containing molecules involving bioactive and functional materials have stimulated the recent development of synthetic methodologies where nucleophilic addition reactions to imino carbons are utilized in crucial steps. This article summarizes double nucleophilic addition reactions with α,β-unsaturated aldimines, addition reactions using alkynyl imines, "umpoled" reactions of α-imino esters, and the use of iminium salts as reactive electrophiles.
