Check Digit Verification of cas no

The CAS Registry Mumber 1647097-04-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,7,0,9 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1647097-04:
(9*1)+(8*6)+(7*4)+(6*7)+(5*0)+(4*9)+(3*7)+(2*0)+(1*4)=188
188 % 10 = 8
So 1647097-04-8 is a valid CAS Registry Number.

Tert-butyl nitrite mediated regiospecific nitration of (E)-azoarenes through palladium-catalyzed directed C - H activation

Majhi, Biju,Kundu, Debasish,Ahammed, Sabir,Ranu, Brindaban C.

supporting information, p. 9862 - 9866 (2014/08/18)

An efficient protocol for the Pd-catalyzed regiospecific ortho-nitration of (E)-azoarenes has been achieved for the first time using tBuONO as a nitrating agent under atmospheric oxygen. A series of both symmetrical and unsymmetrical azoarenes were nitrated efficiently by this procedure providing excellent chemo- and regioselectivity and compatibility with a broad array of functional groups.
