Check Digit Verification of cas no

The CAS Registry Mumber 1639138-00-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,9,1,3 and 8 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1639138-00:
(9*1)+(8*6)+(7*3)+(6*9)+(5*1)+(4*3)+(3*8)+(2*0)+(1*0)=173
173 % 10 = 3
So 1639138-00-3 is a valid CAS Registry Number.

Development of an efficient Pd-catalyzed coupling process for axitinib

Chekal, Brian P.,Guinness, Steven M.,Lillie, Brett M.,McLaughlin, Robert W.,Palmer, Charles W.,Post, Ronald J.,Sieser, Janice E.,Singer, Robert A.,Sluggett, Gregory W.,Vaidyanathan, Rajappa,Withbroe, Gregory J.

, p. 266 - 274 (2014)

The manufacturing process of axitinib (1) involves two Pd-catalyzed coupling reactions, a Migita coupling and a Heck reaction. Optimization of both of these pivotal bond-formation steps is discussed as well as the approach to control impurities in axitinib. Essential to the control strategy was the optimization of the Heck reaction to minimize formation of impurities, in addition to the development of an efficient isolation of crude axitinib to purge impurities.
