Check Digit Verification of cas no

The CAS Registry Mumber 79043-20-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,0,4 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 79043-20:
(7*7)+(6*9)+(5*0)+(4*4)+(3*3)+(2*2)+(1*0)=132
132 % 10 = 2
So 79043-20-2 is a valid CAS Registry Number.

Vanadium-Catalyzed Oxidative Intramolecular Coupling of Tethered Phenols: Formation of Phenol-Dienone Products

Gilmartin, Philip H.,Kozlowski, Marisa C.

supporting information, p. 2914 - 2919 (2020/04/10)

A mild and efficient method for the vanadium-catalyzed intramolecular coupling of tethered free phenols is described. The corresponding phenol-dienone products are prepared directly in good yields with low catalyst loadings. Electronically diverse tethered phenol precursors are well tolerated, and the catalytic method was effectively applied as the key step in syntheses of three natural products and a synthetically useful morphinan alkaloid precursor.
