Check Digit Verification of cas no
The CAS Registry Mumber 201944-90-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,9,4 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 201944-90:
(8*2)+(7*0)+(6*1)+(5*9)+(4*4)+(3*4)+(2*9)+(1*0)=113
113 % 10 = 3
So 201944-90-3 is a valid CAS Registry Number.

, p. 1059 - 1068 (2007/10/03)
Three isotopically labeled tri-p-tolylamines, 15N, 15N2D2, and mono-13CH3, have been prepared using zeolite mediated bromination or nitration of toluenes as one of the key steps. The obtained 4-nitrotoluenes were reduced to 4-aminotoluenes, and coupled, v
