Check Digit Verification of cas no

The CAS Registry Mumber 23938-23-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,9,3 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 23938-23:
(7*2)+(6*3)+(5*9)+(4*3)+(3*8)+(2*2)+(1*3)=120
120 % 10 = 0
So 23938-23-0 is a valid CAS Registry Number.

A general and efficient CuBr2-catalyzed N-arylation of secondary acyclic amides

Wang, Mangang,Yu, Hua,You, Xinwen,Wu, Jun,Shang, Zhicai

, p. 2356 - 2362,7 (2020/09/16)

A general and efficient Cu(II)-catalyzed cross-coupling method is reported for the preparation of acyclic tertiary amides. Generally moderate to excellent yields and functional group tolerance were obtained with secondary acyclic amides and aryl halides as substrates in toluene.
