Check Digit Verification of cas no

The CAS Registry Mumber 1402816-44-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,2,8,1 and 6 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1402816-44:
(9*1)+(8*4)+(7*0)+(6*2)+(5*8)+(4*1)+(3*6)+(2*4)+(1*4)=127
127 % 10 = 7
So 1402816-44-7 is a valid CAS Registry Number.

A copper-mediated tandem reaction through isocyanide insertion into N-H bonds: Efficient access to unsymmetrical tetrasubstituted ureas

Huang, Xiaomei,Xu, Shuguang,Tan, Qitao,Gao, Mingchun,Li, Minjie,Xu, Bin

supporting information, p. 1465 - 1468 (2014/02/14)

A copper-mediated multi-component reaction was developed through isocyanide insertion into N-H bonds of less active secondary arylamines. This approach leads to an efficient synthesis of unsymmetrical tetrasubstituted ureas in one pot. The Royal Society of Chemistry.
