Check Digit Verification of cas no

The CAS Registry Mumber 221526-56-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,5,2 and 6 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 221526-56:
(8*2)+(7*2)+(6*1)+(5*5)+(4*2)+(3*6)+(2*5)+(1*6)=103
103 % 10 = 3
So 221526-56-3 is a valid CAS Registry Number.

An efficient access to the optically active manzamine tetracyclic ring system

Uchida, Hideharu,Nishida, Atsushi,Nakagawa, Masako

, p. 113 - 116 (2007/10/03)

The highly stereoselective synthesis of the optically active tetracyclic core 2 of Manzamine A 1 was achieved via the Diels-Alder reaction of dihydropyridinone 12b, derived from L-serine, with siloxydienes, followed by sequential new and conventional pathways.
