Check Digit Verification of cas no

The CAS Registry Mumber 503617-68-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,6,1 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 503617-68:
(8*5)+(7*0)+(6*3)+(5*6)+(4*1)+(3*7)+(2*6)+(1*8)=133
133 % 10 = 3
So 503617-68-3 is a valid CAS Registry Number.

Design and synthesis of novel heterobiaryl amides as metabotropic glutamate receptor subtype 5 antagonists

Kulkarni, Santosh S.,Newman, Amy Hauck

, p. 2074 - 2079 (2007/10/03)

A series of heterobiaryl amides was designed and synthesized as novel mGluR5 antagonists. The synthesis using palladium catalyzed Suzuki-Miyaura cross-coupling reactions provided an array of compounds with a range of in vitro activities. In particular, compound 9e, 4(3,5-difluorophenyl)-N-(6-methylpyridin-1-yl)picolinamide, exhibited nanomolar affinity at the mGluR5 and will serve as a template for future drug design.
