134414-84-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134414-84-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,4,1 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 134414-84:
(8*1)+(7*3)+(6*4)+(5*4)+(4*1)+(3*4)+(2*8)+(1*4)=109
109 % 10 = 9
So 134414-84-9 is a valid CAS Registry Number.

Imahori, Tatsushi,Hori, Chieko,Kondo, Yoshinori
, p. 1090 - 1092 (2007/10/03)
The addition of O- and N-nucleophiles to alkynes catalyzed by a phosphazene base, t-Bu-P4 base, was investigated. Alkynes were easily transformed to enol ethers and enamines in DMSO by the addition of nucleophiles. When phenylacetylene was reacted with di
