Check Digit Verification of cas no
The CAS Registry Mumber 119204-04-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,2,0 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 119204-04:
(8*1)+(7*1)+(6*9)+(5*2)+(4*0)+(3*4)+(2*0)+(1*4)=95
95 % 10 = 5
So 119204-04-5 is a valid CAS Registry Number.

PALLADIUM-CATALYSED SPIROCYLISATION OF 3-ACETOXY-1-(4-AMINOALKYL)-CYCLOHEXENES
Carruthers, William,Moses, Roger C.
, p. 2255 - 2258 (2007/10/02)
The 2,7-disubstituted 1-azaspiroundecene (2; R = pentyl, R1 = Bu) cannot be obtained by Pd0-catalysed cyclisation of the cyclohexyl acetate (1; R = pentyl, R1 = Bu), but the monosubstituted derivative (2; R = H, Rsup
