Check Digit Verification of cas no

The CAS Registry Mumber 1291099-39-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,1,0,9 and 9 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1291099-39:
(9*1)+(8*2)+(7*9)+(6*1)+(5*0)+(4*9)+(3*9)+(2*3)+(1*9)=172
172 % 10 = 2
So 1291099-39-2 is a valid CAS Registry Number.

Pyrrole macrocyclic ligands for Cu-catalyzed asymmetric henry reactions

Gualandi, Andrea,Cerisoli, Lucia,Stoeckli-Evans, Helen,Savoia, Diego

, p. 3399 - 3408 (2011)

New chiral perazamacrocycles containing four pyrrole rings have been synthesized by the [2 + 2] condensation of (R,R)-diaminocyclohexane and 5,5′-(alkane-2,2-diyl)bis(1H-pyrrole-2-carbaldehydes). These macrocycles, differing for the alkyl/aryl meso-substi
