129409-90-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129409-90-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,4,0 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 129409-90:
(8*1)+(7*2)+(6*9)+(5*4)+(4*0)+(3*9)+(2*9)+(1*0)=141
141 % 10 = 1
So 129409-90-1 is a valid CAS Registry Number.

A Route to Vicinal Diamines from the Samarium(II) Iodide-Mediated Coupling of Aldimines
Enholm, Eric J.,Forbes, David C.,Holub, David P.
, p. 981 - 987 (2007/10/02)
A new method to construct vicinal diamines from aldimines mediated by the one electron reductant, samarium diiodide is described.The reaction probably involves a ketyl-like radical coupling mechanism.
