Check Digit Verification of cas no

The CAS Registry Mumber 108972-05-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,9,7 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 108972-05:
(8*1)+(7*0)+(6*8)+(5*9)+(4*7)+(3*2)+(2*0)+(1*5)=140
140 % 10 = 0
So 108972-05-0 is a valid CAS Registry Number.

Rapid, Operationally Simple, and Metal-free NBS Mediated One-pot Synthesis of 1,2-Naphthoquinone from 2-Naphthol

Sim, Jaeuk,Jo, Hyeju,Viji, Mayavan,Choi, Minho,Jung, Jin-Ah,Lee, Heesoon,Jung, Jae-Kyung

, p. 852 - 858 (2018)

A metal-free, one-pot synthesis of 1,2-naphthoquinone was accomplished from 2-naphthol by utilizing economically cheap NBS under open air conditions. Initial formation of 1,1-dibromonaphthalen-2-one and subsequent transformation afforded the 1,2-naphthoquinone. This oxidation was completed within 30 min and had broad substrate scope. Moreover, this system tolerated heterocyclic systems and was also applicable to 1,3-dicarbonyl systems. This practical approach with short reaction times, a simple workup, and insensitivity to moisture could override the usage of expensive and hazardous oxidizing and metal reagents. (Figure presented.).
