Check Digit Verification of cas no

The CAS Registry Mumber 946428-55-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,6,4,2 and 8 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 946428-55:
(8*9)+(7*4)+(6*6)+(5*4)+(4*2)+(3*8)+(2*5)+(1*5)=203
203 % 10 = 3
So 946428-55-3 is a valid CAS Registry Number.

Regio- and stereoselective heck arylations of N-carbomethoxy-L-3- dehydroproline methyl ester with arenediazonium salts. Total synthesis of neuroexcitatory aryl kainoids

Da Silva, Kezia Peixoto,Godoi, Marla Narciso,Correia, Carlos Roque Duarte

, p. 2815 - 2818 (2008/02/05)

The Heck arylation of N-carbomethoxy-L-3-dehydroproline methyl ester with arenediazonium tetrafluoroborates produced chiral 4-aryldehydroproline derivatives in moderate to good yields in a highly regio- and stereocontrolled fashion. A rationale for the un
