Check Digit Verification of cas no
The CAS Registry Mumber 200411-27-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,4,1 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 200411-27:
(8*2)+(7*0)+(6*0)+(5*4)+(4*1)+(3*1)+(2*2)+(1*7)=54
54 % 10 = 4
So 200411-27-4 is a valid CAS Registry Number.

5-endo-trig Cyclisations in heterocycle synthesis: Enantiospecific synthesis of (+)-monomorine I
Berry, Malcolm B.,Craig, Donald,Jones, Philip S.,Rowlands, Gareth J.
, p. 2141 - 2142 (2007/10/03)
The indolizidine alkaloid monomorine I is synthesised from D-norleucinol using 5-endo-trig cyclisation and intramolecular reductive amination as the key ring-forming steps.
