Check Digit Verification of cas no

The CAS Registry Mumber 73139-89-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,1,3 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 73139-89:
(7*7)+(6*3)+(5*1)+(4*3)+(3*9)+(2*8)+(1*9)=136
136 % 10 = 6
So 73139-89-6 is a valid CAS Registry Number.

supporting information, p. 7701 - 7704 (2021/08/09)

An efficient annulation reaction of aurone-derived α,β-unsaturated imines and activated terminal alkynes mediated by triethylamine is described, which enables the facile synthesis of 1,4-dihydrobenzofuro[3,2-b]pyridines in high yields. When the nucleophil

Design, synthesis and MAO inhibitory activity of 2-(arylmethylidene)-2,3-dihydro-1-benzofuran-3-one derivatives

supporting information, p. 1528 - 1532 (2017/07/17)

A series of 2-(arylmethylidene)-2,3-dihydro-1-benzofuran-3-one derivatives (aurones, 1–20) were synthesized and screened for their inhibitory activity against hMAO. Seventeen compounds (1–5, 7–17, 19) were found to be selective towards hMAO-B, while two w
