Check Digit Verification of cas no

The CAS Registry Mumber 1128-57-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,2 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1128-57:
(6*1)+(5*1)+(4*2)+(3*8)+(2*5)+(1*7)=60
60 % 10 = 0
So 1128-57-0 is a valid CAS Registry Number.

Nucleophilic deoxyfluorination of catechols

Nemoto, Hiroyuki,Nishiyama, Tsuyoshi,Akai, Shuji

supporting information; experimental part, p. 2714 - 2717 (2011/06/28)

Nucleophilic deoxyfluorinaiton of one of the two hydroxyl groups of catechols has been developed via the Umpolung concept. This method was successively applied to naturally occurring catechols, such as catechins and dopamine, to produce novel fluorinated

Highly substituted Schiff base macrocycles via hexasubstituted benzene: a convenient double Duff formylation of catechol derivatives

Shopsowitz, Kevin E.,Edwards, David,Gallant, Amanda J.,MacLachlan, Mark J.

scheme or table, p. 8113 - 8119 (2009/12/09)

The synthesis of soluble, shape-persistent macrocycles is important for developing new materials. Double Duff formylation of 4,5-dialkylcatechol derivatives yields 3,6-diformyl-4,5-dialkylcatechols in moderate yields. These hexasubstituted aromatics are u

Chemistry of 2-Methoxy-2,5-cyclohexadienones. I. Photochemistry of 2-Methoxy-4,4-dimethyl-2,5-cyclohexadienone

Matoba, Katsuhide,Karibe, Norio,Yamazaki, Takao

, p. 3906 - 3911 (2007/10/02)

The title compound, 2-methoxy-4,4-dimethyl-2,5-cyclohexadienone (V), was prepared from 2-methoxy-4,4-dimethyl-2-cyclohexenone (VIa).A methanolic solution of V was irradiated with a 200 W mercury lamp at -3 deg C to give 2,2-dimethoxy-6,6-dimethylbicyclo3
