Check Digit Verification of cas no

The CAS Registry Mumber 1040129-98-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,0,1,2 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1040129-98:
(9*1)+(8*0)+(7*4)+(6*0)+(5*1)+(4*2)+(3*9)+(2*9)+(1*8)=103
103 % 10 = 3
So 1040129-98-3 is a valid CAS Registry Number.

Synthesis of symmetrical and unsymmetrical N-aryl-substituted cyclic ureas through copper(I) iodide catalyzed Goldberg-Buchwald-Nandakumar C-N coupling reactions

Lee, Chung-Chieh,Wang, Po-Shih,Viswanath, M. Balaji,Leung, Man-Kit

, p. 1359 - 1366 (2008/12/21)

The catalytic conditions of copper(I) iodide/potassium carbonate/trans-N, N′-dimethylcyclohexane-1,2-diamine, either in toluene at reflux temperature, or by heating neat at 150°C effectively promoted the C-N coupling of aryl bromides with cyclic ureas. By
