74107-90-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74107-90-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,0 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74107-90:
(7*7)+(6*4)+(5*1)+(4*0)+(3*7)+(2*9)+(1*0)=117
117 % 10 = 7
So 74107-90-7 is a valid CAS Registry Number.

Butatrien durch Thermolyse von Propiolsaeure-(2-propinyl)ester

Bilinski, Vanda,Dreiding, Andre S.,Hollenstein, Hans

, p. 2322 - 2329 (2007/10/02)

Flow thermolysis of 2-propynyl propiolate (5) at 580 deg C afforded butatriene (6) (ca. 50percent) and as by-products, 4-methylene-2-cyclobuten-1-one (7), 2-ethynylpropenal (8), 1-penten-4-yn-3-one (9), 4-penten-2-ynal (10) (tottal ca. 10percent), along with some propynal, acetylene, CO2 and CO.In the same way, propiolic acid (1,1-D2)-2-propynyl propiolate (11) led to (1,1-D2)-butatriene (12) and a litle 4-((D2)methylene)-2-cyclobuten-1-one (13).A mechanism is proposed for the transformation of 5 into 6 and of 11 into 12, which also accounts for the formation of 7, 8, 9 and 10, as well as 13.The position of one of the published 13C-NMR signal of butatriene (6) must be revised.Thermolysis of methyl-(1) and ethyl propiolate (2) resulted in small yields of 2-buten-4-olide (3) and 2-penten-4-olide (4).
