Check Digit Verification of cas no

The CAS Registry Mumber 1352050-49-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,2,0,5 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1352050-49:
(9*1)+(8*3)+(7*5)+(6*2)+(5*0)+(4*5)+(3*0)+(2*4)+(1*9)=117
117 % 10 = 7
So 1352050-49-7 is a valid CAS Registry Number.

Heterogeneous bimetallic Pt-Sn/γ-Al2O3 catalyzed direct synthesis of diamines from N-alkylation of amines with diols through a borrowing hydrogen strategy

Wang, Liandi,He, Wei,Wu, Kaikai,He, Songbo,Sun, Chenglin,Yu, Zhengkun

supporting information; experimental part, p. 7103 - 7107 (2012/01/05)

Direct synthesis of diamines has been efficiently realized from the N-alkylation of amines with diols by means of heterogeneous bimetallic Pt-Sn/γ-Al2O3 catalyst (0.5 wt % Pt, molar ratio Pt:Sn = 1:3) through a 'Borrowing Hydrogen' strategy under ligand-free conditions. The present methodology provides an environmentally benign route to diamines.
