Check Digit Verification of cas no

The CAS Registry Mumber 108718-21-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,7,1 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 108718-21:
(8*1)+(7*0)+(6*8)+(5*7)+(4*1)+(3*8)+(2*2)+(1*1)=124
124 % 10 = 4
So 108718-21-4 is a valid CAS Registry Number.

Selectfluor-mediated oxidative methylenation of amide with N, N -dimethylpropanamide for N, N ′-methylenebisamide synthesis

Cao, Yue,Zhou, Dongheng,Ma, Yongmin

, p. 37 - 41 (2019/01/10)

A simple and efficient approach for the synthesis of N,N′-methylenebisamides through a Selectfluor-mediated oxidative reaction of aromatic amides and N,N-dimethylpropanamide (DMP) is described. Remarkable results clearly reveal that DMP plays a dual role in this reaction, as both a one-carbon source and an environment-friendly solvent. Moreover, the process provides new strategies for the synthesis of bisamides with advantages of operationally simple, insensitive to atmospheric conditions, and good to high yields.
