198222-13-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 198222-13-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,2,2 and 2 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 198222-13:
(8*1)+(7*9)+(6*8)+(5*2)+(4*2)+(3*2)+(2*1)+(1*3)=148
148 % 10 = 8
So 198222-13-8 is a valid CAS Registry Number.

Reactions of alkylidenephosphoranes with symmetrically substituted p-quinones

Abdou, Wafaa M.,Salem, Monier A. E.,Sediek, Ashraf A.

, p. 13945 - 13958 (1997)

The reaction of p-quinone 1 with ylides 2a and 2b afforded the corresponding phosphonium salts 8a,b, p-quinone-dimethanides 4a,b(Z) and 5a,b(E); substituted phenols 7a,b(Z and E) and coumarin-derivative 11 (only with 2a). The reaction of 1 with ylide 2c gave, besides 4c, 5c and 8c, hydroquinone[1]cyclobutene 16 and the Diels-Alder product 17. Reactions of 1 with 2d and 3 (salts) in the presence of sodium alkoxide yielded through preferred attack on the nitrile function, azo-22 and bisimino-24 compounds, respectively.
