Check Digit Verification of cas no

The CAS Registry Mumber 1026885-57-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,6,8,8 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1026885-57:
(9*1)+(8*0)+(7*2)+(6*6)+(5*8)+(4*8)+(3*5)+(2*5)+(1*7)=163
163 % 10 = 3
So 1026885-57-3 is a valid CAS Registry Number.

CuI-catalyzed coupling reaction of beta-amino acids or esters with aryl halides at temperature lower than that employed in the normal Ullmann reaction. Facile synthesis of SB-214857.

Ma,Xia

, p. 2583 - 2586 (2007/10/03)

[reaction: see text] The CuI-catalyzed coupling reaction of aryl halides with beta-amino acids or beta-amino esters is completed at 100 degrees C in 48 h, which indicates that the structure of the beta-amino acid has an accelerating effect for the Ullmann
