Check Digit Verification of cas no
The CAS Registry Mumber 2067-80-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,6 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2067-80:
(6*2)+(5*0)+(4*6)+(3*7)+(2*8)+(1*0)=73
73 % 10 = 3
So 2067-80-3 is a valid CAS Registry Number.

Electrocatalytic C-N coupling reaction by co-activation of both N2 and CO2 molecules under ambient conditions to synthesize valuable urea opens a new avenue for sustainable development, while the actual catalytic activity is limited by poor adsorption and coupling capability of gas molecules on the catalyst surface. Herein, theoretical calculation predicts that the well-developed built-in electric field in perovskite hetero-structured BiFeO3/BiVO4 hybrids can accelerate the local charge redistribution and thus promote the targeted adsorption and activation of inert N2 and CO2 molecules on the generated local electrophilic and nucleophilic regions. Thus, a BiFeO3/BiVO4 heterojunction is designed and synthesized, which delivers a urea yield rate of 4.94 mmol h-1 g-1 with a faradaic efficiency of 17.18% at -0.4 V vs. RHE in 0.1 M KHCO3, outperforming the highest values reported as far. The comprehensive analysis further confirms that the local charge redistribution in the heterojunction effectively suppresses CO poisoning and the formation of the endothermic ?NNH intermediate, which thus guarantees the exothermic coupling of ?NN? intermediates with the generated CO via C-N coupling reactions to form the urea precursor ?NCON? intermediate. This work opens a new avenue for effective electrocatalytic C-N coupling under ambient conditions.
