Check Digit Verification of cas no

The CAS Registry Mumber 1564241-89-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,4,2,4 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1564241-89:
(9*1)+(8*5)+(7*6)+(6*4)+(5*2)+(4*4)+(3*1)+(2*8)+(1*9)=169
169 % 10 = 9
So 1564241-89-9 is a valid CAS Registry Number.

Palladium nanoparticles catalyzed Sonogashira reactions for the one-pot synthesis of symmetrical and unsymmetrical diarylacetylenes

Mandali, Pavan Kumar,Chand, Dillip Kumar

, p. 40 - 44 (2014)

A variety of symmetrical and unsymmetrical diarylacetylenes are synthesized by ligand-free palladium nanoparticles catalyzed copper-free and amine-free Sonogashira cross-coupling reactions between aryl iodides and trimethylsilylacetylene (TMSA) under mild reaction conditions.
