Check Digit Verification of cas no
The CAS Registry Mumber 143317-90-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,3,1 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143317-90:
(8*1)+(7*4)+(6*3)+(5*3)+(4*1)+(3*7)+(2*9)+(1*0)=112
112 % 10 = 2
So 143317-90-2 is a valid CAS Registry Number.

Ru/C catalyzed cyclization of linear α,ω-diamines to cyclic amines in water
G?dda, Thomas M.,Yu, Xiao-Yan,Miyazawa, Akira
, p. 1249 - 1253 (2010)
A facile and convenient way to prepare cyclic amines in water was achieved by the catalyst system composed of Ru/C and Al powder. The α,ω-diaminoalkanes, 1,4-diaminobutane, 1,5-diaminopentane, and 1,6-diamino-heptane were converted to corresponding cyclic amines in good yields. The use of D2O provided a novel route to obtain deuterated cyclic amines in good yields.
