Check Digit Verification of cas no

The CAS Registry Mumber 190851-63-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,8,5 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 190851-63:
(8*1)+(7*9)+(6*0)+(5*8)+(4*5)+(3*1)+(2*6)+(1*3)=149
149 % 10 = 9
So 190851-63-9 is a valid CAS Registry Number.

Aryliodonium derivatives of 2-amino-1,4-quinones: Preparation and reactivity

Papoutsis, Ioannis,Spyroudis, Spyros,Varvoglis, Anastasios,Raptopoulou, Catherine P.

, p. 6097 - 6112 (1997)

The reaction of 2-amino-1,4-quinones with [(hydroxy)(tosyloxy)iodo]arenes affords stable 2-amino-3-aryliodonio-1,4- quinones in high yields. The latter, upon treatment with alkali, are converted to the corresponding zwitterionic 3-aryliodonio-1,4-quinone-2-imides. This new class of compounds exhibits an interesting reactivity: upon heating, aryl migration from iodine to nitrogen is observed, while photochemical reaction with aromatic compounds and 2,3-dihydrofuran leads to substitution products. Nucleophilic attack of sodium alkoxides on these zwitterions results in opening of the quinone ring affording synthetically interesting multifunctional products.
