Check Digit Verification of cas no

The CAS Registry Mumber 497845-65-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,7,8,4 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 497845-65:
(8*4)+(7*9)+(6*7)+(5*8)+(4*4)+(3*5)+(2*6)+(1*5)=225
225 % 10 = 5
So 497845-65-5 is a valid CAS Registry Number.

Convenient synthesis of polyfunctionalized β-fluoropyrroles from rhodium(II)-catalyzed intramolecular N-H insertion reactions

Wang, Yanli,Zhu, Shizheng

, p. 745 - 748 (2007/10/03)

(Matrix presented) Polyfunctionalized β-fluoropyrrole can be readily prepared from rhodium(II) acetate-catalyzed intramolecular N-H insertion reaction of δ-amino-γ,γ-difluoro-α-diazo-β -ketoesters. A cyanomethylene group can be introduced at C-3 of the py

A convenient synthetic access to δ-amino-γ,γ-difluoro-β-ketoesters

Wang, Yanli,Zhu, Shizheng

, p. 1813 - 1818 (2007/10/03)

The zinc-cuprous chloride promoted Reformatsky-imine addition reaction of 4-bromo-4,4-difluoroacetoacetate with aldimines derived from aromatic aldehydes and with ketimines derived from aryl alkyl ketone provided an efficient and practical access to δ-amino-γ,γ-difluoro-β-ketoesters. The scope and limitation of this procedure are also discussed.
