Check Digit Verification of cas no

The CAS Registry Mumber 32547-98-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,5,4 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 32547-98:
(7*3)+(6*2)+(5*5)+(4*4)+(3*7)+(2*9)+(1*8)=121
121 % 10 = 1
So 32547-98-1 is a valid CAS Registry Number.

Synthesis of 1,2,3-triazole-fused heterocycles via Pd-catalyzed cyclization of 5-iodotriazoles

Schulman, Jacqueline M.,Friedman, Adam A.,Panteleev, Jane,Lautens, Mark

, p. 55 - 57 (2012/01/05)

A convenient approach toward polycyclic frameworks containing fused 1,2,3-triazoles is described. The synthesis consists of a Cu-catalyzed cycloaddition and an intramolecular Pd-catalyzed direct arylation or Heck reaction, and affords the products in good to excellent yields.
