Check Digit Verification of cas no

The CAS Registry Mumber 129680-22-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,6,8 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 129680-22:
(8*1)+(7*2)+(6*9)+(5*6)+(4*8)+(3*0)+(2*2)+(1*2)=144
144 % 10 = 4
So 129680-22-4 is a valid CAS Registry Number.

Process for preparing TCD-diamine

-

Page/Page column 6-7, (2008/06/13)

A process for preparing 3(4),8(9)-bis(aminomethyl)tricycle-[5.2.1.02,6]decane by hydroformylating dicyclopentadiene with subsequent reductive amination wherein the hydroformylation of dicyclopentadiene is carried out in two stages, and, in a first hydroformylation stage, the reaction is effected in a heterogeneous reaction system using an aqueous solution of transition metal compounds, containing water-soluble organic phosphorus (III) compounds in complex-bound form, of group VIII of the Periodic Table to give 8(9)-formyltricyclo[5.2.1.02,6]dec-3-ene, and, in a second hydroformylation stage, the thus obtained 8(9)-formyltricyclo[5.2.1.02,6]dec-3-ene is converted, in a homogeneous organic phase in the presence of transition metal compounds of group VIII of the Periodic Table of the Elements to 3(4),8(9)-bisformyltricyclo[5.2.1.02,6]decane
