Check Digit Verification of cas no

The CAS Registry Mumber 1289513-42-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,9,5,1 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1289513-42:
(9*1)+(8*2)+(7*8)+(6*9)+(5*5)+(4*1)+(3*3)+(2*4)+(1*2)=183
183 % 10 = 3
So 1289513-42-3 is a valid CAS Registry Number.

Synthetic studies towards pectenotoxin-2: Synthesis of the nonanomeric 10-epi-ABCDE ring segment by kinetic spiroketalization

Aho, Jatta E.,Piisola, Antti,Syam Krishnan,Pihko, Petri M.

, p. 1682 - 1694 (2011/05/04)

The synthesis of the nonanomeric 10-epi-ABCDE ring system of pectenotoxin-2 has been achieved by using a kinetic spiroketalization reaction. The synthesis of the spiroketalization precursor was achieved through a cross-metathesis/ hydrogenation sequence.
