Check Digit Verification of cas no

The CAS Registry Mumber 672303-41-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,2,3,0 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 672303-41:
(8*6)+(7*7)+(6*2)+(5*3)+(4*0)+(3*3)+(2*4)+(1*1)=142
142 % 10 = 2
So 672303-41-2 is a valid CAS Registry Number.

LiClO4-Activated stereo- and regioselective alkylation of aldehydes

Markert,Buchem,Krüger,Mahrwald

, p. 993 - 999 (2004)

Aldehydes undergo an unusual and very mild alkylation by LiClO 4-activation in the presence of acids. This new methodology enables the inclusion of a broad range of aldehydes as well as tertiary alcohols. Regio- and stereoselectivity observed during this reaction will be discussed.

A new approach to 2,2-disubstituted chromenes and tetrahydroquinolines through intramolecular cyclization of chiral 3,4-epoxy alcohols

Goujon, Jean-Yves,Zammattio, Fran?oise,Chrétien, Jean-Mathieu,Beaudet, Isabelle

, p. 4037 - 4049 (2007/10/03)

An efficient route to chiral chromene and tetrahydroquinoline ring models 3 and 4 was developed by means of the vanadium epoxidation of chiral homoallylic alcohols 12 and 19 followed by an intramolecular epoxide opening of 3,4-epoxy alcohols 14 and 20. Th
