Check Digit Verification of cas no

The CAS Registry Mumber 104750-77-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,7,5 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 104750-77:
(8*1)+(7*0)+(6*4)+(5*7)+(4*5)+(3*0)+(2*7)+(1*7)=108
108 % 10 = 8
So 104750-77-8 is a valid CAS Registry Number.

NITROCYCLOHEXADIENONES : CONVENIENT NEW MONO-NITRATING AGENTS FOR AROMATIC COMPOUNDS

Roussel, J.,Lemaire, M.,Guy, A.,Guette, J.P.

, p. 27 - 28 (1986)

Nitrocyclohexadienones are effective nitrating agents for naphtols in dry ether at room temperature to give good yields of mononitrated products.

The Nitration of some 4-Alkylphenols; Acid-Catalysed Rearrangements of Some Polysubstituted 4-Alkyl-4-hydroxycyclohexa-2,5-dienones

Gray, Michael J.,Hartshorn, Michael P.,Vaughan, John

, p. 59 - 68 (2007/10/02)

The nitrations of 4-methyl (6a) and 4-ethyl (9a) tetrabromo phenols, and 4-methyl (6b) and 4-ethyl (9b) 2,3,5-tribromo-6-nitrophenols are described.The acid-catalysed rearrangements of 4-alkyl-4-hydroxycyclohexa-2,5-dienones (7a,b) and (8a,b) in concentrated sulfuric acid are described, and the effects of the nature of the C4-alkyl group and C6-substituent (Br or NO2) on the observed reactions are discussed.
