220575-20-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220575-20-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,5,7 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 220575-20:
(8*2)+(7*2)+(6*0)+(5*5)+(4*7)+(3*5)+(2*2)+(1*0)=102
102 % 10 = 2
So 220575-20-2 is a valid CAS Registry Number.

Concise synthesis of nitidine by palladium-assisted biaryl coupling reaction
Harayama, Takashi,Shibaike, Kentaro
, p. 191 - 195 (2007/10/03)
Formal total synthesis of nitidine (1) was accomplished via oxynitidine (7) by the internal aryl-aryl coupling reaction of iodo-amide (6) using palladium-assisted cyclization reaction.
