Check Digit Verification of cas no

The CAS Registry Mumber 139976-68-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,7 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 139976-68:
(8*1)+(7*3)+(6*9)+(5*9)+(4*7)+(3*6)+(2*6)+(1*8)=194
194 % 10 = 4
So 139976-68-4 is a valid CAS Registry Number.

First Evidence of Unhindered Silanimines Obtained by Flash Vacuum Thermolysis and Vacuum Gas-Solid Reaction

Denis, Jean-Marc,Guenot, Pierre,Letulle, Marguerite,Pellerin, Bruno,Ripoll, Jean-Louis

, p. 1397 - 1400 (2007/10/02)

The unhindered silanimines 1,1-dimethyl-N-phenylsilanimine (2) and N-isopropyl-1,1-dimethylsilanimine (10) have been generated by flash vacuum thermolysis of the N-allylsilanamine 1 and vacuum gas-solid reaction of the 1-chlorosilanamine 9, respectively.The silanimines 2 and 10 have been characterized by MS as well as by chemical trapping to yield 3 or dimerization to the cyclodisilazane 11.Key Words: Flash vacuum thermolysis / Retro-ene reaction / Silanamine / Silanimine / Vacuum gas solid reaction
