Check Digit Verification of cas no

The CAS Registry Mumber 531512-51-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,3,1,5,1 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 531512-51:
(8*5)+(7*3)+(6*1)+(5*5)+(4*1)+(3*2)+(2*5)+(1*1)=113
113 % 10 = 3
So 531512-51-3 is a valid CAS Registry Number.

Solid-phase synthesis of five-dimensional libraries via a tandem Petasis-Ugi multi-component condensation reaction

Portlock, David E.,Naskar, Dinabandhu,West, Laura,Ostaszewski, Ryszard,Chen, Jack J.

, p. 5121 - 5124 (2003)

Five-dimensional libraries of dipeptide amides are readily prepared using a solid-phase tandem Petasis-Ugi multi-component condensation protocol on either a RINK amine or Universal RINK isonitrile resin. The method is practical and can be automated to prepare a large number of compounds useful for high throughput biological screening.
