Check Digit Verification of cas no

The CAS Registry Mumber 202190-87-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,1,9 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 202190-87:
(8*2)+(7*0)+(6*2)+(5*1)+(4*9)+(3*0)+(2*8)+(1*7)=92
92 % 10 = 2
So 202190-87-2 is a valid CAS Registry Number.

The [Cu]-catalyzed SNAR reactions: Direct amination of electron deficient aryl halides with sodium azide and the synthesis of arylthioethers under Cu(II) - Ascorbate redox system

Goriya, Yogesh,Ramana

experimental part, p. 7642 - 7650 (2010/12/19)

A one pot [Cu]-promoted SNAr reaction of electron-deficient halobenzenes with sodium azide and the reduction of the intermediate aryl azides under the same Cu(II)-ascorbate redox conditions leading to anilines has been documented. Control experiments revealed that both ascorbate and proline play important role in the reaction path way. Further, the use of this catalytic Cu(II)-ascorbate redox system has been explored for the synthesis of arylthioethers.
