Check Digit Verification of cas no
The CAS Registry Mumber 132256-86-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,2,5 and 6 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 132256-86:
(8*1)+(7*3)+(6*2)+(5*2)+(4*5)+(3*6)+(2*8)+(1*6)=111
111 % 10 = 1
So 132256-86-1 is a valid CAS Registry Number.

Synthesis of (-)-Slaframine and Related Indolizidines
Pearson, William H.,Bergmeier, Stephen C.,Williams, John P.
, p. 3977 - 3987 (2007/10/02)
An enantioselective synthesis of the indolizidine alkaloid (-)-slaframine 1 is reported.Reductive double cyclization of the azido epoxy tosylate 48 afforded the indolizidine 52, which was converted to (-)-slaframine in two steps.The cyclization substrate
