Check Digit Verification of cas no

The CAS Registry Mumber 99309-11-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,3,0 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 99309-11:
(7*9)+(6*9)+(5*3)+(4*0)+(3*9)+(2*1)+(1*1)=162
162 % 10 = 2
So 99309-11-2 is a valid CAS Registry Number.

Convergent Functional Groups: Synthetic and Structural Studies

Rebek, Julius Jr.,Marshall, Luann,Wolak, Raymond,Parris, Kevin,Killoran, Mary,et al.

, p. 7476 - 7481 (1985)

The synthesis of new molecular systems in which carboxyl groups are directed at well-defined microenvironments is described.The structures are obtained by condensation of suitable aromatic diamines with triacid 4a.Crystallographic studies establish the structural details of the systems and lead to the design and preparation of systems featuring a molecular cleft.These new molecules resemble enzymes in which carboxyl groups converge at the active sites.
