219781-99-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 219781-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,7,8 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 219781-99:
(8*2)+(7*1)+(6*9)+(5*7)+(4*8)+(3*1)+(2*9)+(1*9)=174
174 % 10 = 4
So 219781-99-4 is a valid CAS Registry Number.

Synthesis of benzo[c]phenanthridine alkaloids, using a novel palladium-phosphine combination system - Pd(OAc)2, DPPP, and Bu3P

Harayama, Takashi,Akiyama, Toshihiko,Nakano, Yuichiro,Shibaike, Kentaro,Akamatsu, Hisashi,Hori, Akihiro,Abe, Hitoshi,Takeuchi, Yasuo

, p. 237 - 241 (2007/10/03)

Total synthesis of several benzo[c]phenanthridine alkaloids was accomplished via an aryl-aryl coupling reaction using a novel Pd reagent prepared from Pd(OAc)2 DPPP, and Bu3P. This is a versatile method for the coupling reactions of not only aryl triflates and arenes but also aryl halides and arenes.

Synthesis of benzo[c]phenanthridine alkaloids, chelerythrine and nitidine, using a novel palladium-phosphine combination system -Pd(OAc)2, DPPP, and Bu3P-

Harayama, Takashi,Akiyama, Toshihiko,Nakano, Yuichiro,Shibaike, Kentaro

, p. 1989 - 1992 (2007/10/03)

Total synthesis of chelerythrine (1) and nitidine (4) was accomplished via the aryl-aryl cyclization reaction using a novel Pd reagent prepared from Pd(OAc)2, DPPP, and Bu3P. The present method was very versatile for coupling reaction not only between aromatic inflate and arene but also between aromatic halide and arene.
