125878-99-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 125878-99-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,8,7 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 125878-99:
(8*1)+(7*2)+(6*5)+(5*8)+(4*7)+(3*8)+(2*9)+(1*9)=171
171 % 10 = 1
So 125878-99-1 is a valid CAS Registry Number.

Palladium-Catalyzed Ring Closure Reactions to Benzofuranes: A New and Effective Approach to Azacoumestrols

Stadlbauer, Wolfgang,Laschober, Rita,Kappe, Thomas

, p. 531 - 539 (2007/10/02)

Azacoumestans (benzofuroquinolinones) 4 have been synthesized using the following three methods: ring closure of 3-aryl-4-hydroxy-2-quinolones 3a-e by Pd-catalyzed cyclodehydrogenation, ring closure of 3-hydroxy-3-aryl-2,4-quinolinediones 5 by acid-catalyzed cyclodehydratation, or ring closure of 4-aryloxy-3-iodo-quinolones 8, which are obtained by rearrangement of iodonium ylides 7, by palladium-mediated cyclodehydrohalogenation.Only the latter reaction yielded the coumestrol analog dimethoxy derivatives 4c, d, which have been transformed into the hydroxy and acetoxy derivatives 9, 10.
