153944-51-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 153944-51-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,9,4 and 4 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 153944-51:
(8*1)+(7*5)+(6*3)+(5*9)+(4*4)+(3*4)+(2*5)+(1*1)=145
145 % 10 = 5
So 153944-51-5 is a valid CAS Registry Number.

Synthesis of the lipophilic antifolate piritrexim via a palladium(0)-catalyzed cross-coupling reaction
Chan, David C. M.,Rosowsky, Andre
, p. 1364 - 1368 (2005)
(Chemical Equation Presented) A regiospecific and convergent route the lipophilic antifolate piritrexim (PTX) is described in which a key step is a Pd(0)-catalyzed cross-coupling reaction between 2-amino-3-cyano-4-methyl-5- bromopyridine and 2,5-dimethoxy
