128581-40-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128581-40-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,8 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 128581-40:
(8*1)+(7*2)+(6*8)+(5*5)+(4*8)+(3*1)+(2*4)+(1*0)=138
138 % 10 = 8
So 128581-40-8 is a valid CAS Registry Number.

Black, David St C.,Keller, Paul A.,Kumar, Naresh
, p. 5807 - 5808 (2007/10/02)
Pyrrolophenanthridone alkaloids were easily synthesized by palladium acetate catalyzed arylation of N-acylindolines (5a-c) followed by dehydrogenation.
