572912-39-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 572912-39-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,7,2,9,1 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 572912-39:
(8*5)+(7*7)+(6*2)+(5*9)+(4*1)+(3*2)+(2*3)+(1*9)=171
171 % 10 = 1
So 572912-39-1 is a valid CAS Registry Number.

Daab, Jochen C.,Bracher, Franz
, p. 573 - 583 (2007/10/03)
The indolizidinium alkaloid ipalbidinium and the quinolizidinium alkaloid clathryimine B were prepared starting from brominated 2-aminopyridines using two Pd-catalyzed cross-coupling reactions and a Sandmeyer-type diazotation/iodination protocol as the key steps.
