7003-20-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7003-20-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,0 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7003-20:
(6*7)+(5*0)+(4*0)+(3*3)+(2*2)+(1*0)=55
55 % 10 = 5
So 7003-20-5 is a valid CAS Registry Number.

Efficient oxidative N-dealkylative addition of trialkylamines to dimethyl acetylenedicarboxylate using BrCCl3 as the terminal oxidant

Liu, Fangnan,Zhang, Zhiguo,Bao, Zongbi,Xing, Huabin,Yang, Yiwen,Ren, Qilong

, p. 2707 - 2710 (2017)

Herein we present a continuous improvement of visible-light mediated N-dealkylative addition of tertiary amines to dimethyl acetylenedicarboxylates (DMAD) using alkyl halogenides as external oxidants together with base additives. This method is highlighted by excellent tolerance with various tertiary amines and good to excellent yields in short reaction time under mild conditions.
