Check Digit Verification of cas no
The CAS Registry Mumber 205116-01-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,1,1 and 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 205116-01:
(8*2)+(7*0)+(6*5)+(5*1)+(4*1)+(3*6)+(2*0)+(1*1)=74
74 % 10 = 4
So 205116-01-4 is a valid CAS Registry Number.

An efficient and stereoselective construction of the core structure of the manzamines via an intramolecular Michael reaction
Brands,DiMichele
, p. 1677 - 1680 (2007/10/03)
A strategically functionalized tricyclic subunit of the manzamines was efficiently synthesized with complete stereochemical control using a combination of an intramolecular Michael reaction of a pyroglutamic acid derivative and a hydrogenation.
