Check Digit Verification of cas no

The CAS Registry Mumber 90702-06-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,7,0 and 2 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 90702-06:
(7*9)+(6*0)+(5*7)+(4*0)+(3*2)+(2*0)+(1*6)=110
110 % 10 = 0
So 90702-06-0 is a valid CAS Registry Number.

Catalyst and Additive-Free Direct Amidation/Halogenation of Tertiary Arylamines with N-haloimide/amides

Xu, Xiu-Juan,Amuti, Adila,Wusiman, Abudureheman

, p. 5002 - 5008 (2020)

An approach has been developed for the amidation (halogenation) of tertiary arylamines by electrophilic activation using N-haloimide/amides. Several control experiments have been performed, and the coupling reaction outcomes indicated that the N-haloimide/amide brings three major functions, including electrophilic activation, aromatic halogenation and nucleophilic nitrogen sources. This cascade reaction features simple manipulation, requires no additional catalyst, oxidant or additives, and is performed under mild conditions. (Figure presented.).
