13504-72-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13504-72-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,0 and 4 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 13504-72:
(7*1)+(6*3)+(5*5)+(4*0)+(3*4)+(2*7)+(1*2)=78
78 % 10 = 8
So 13504-72-8 is a valid CAS Registry Number.

Synthesis of Conjugated Alkynenitriles

Yalda, R,Rao, V. Subrahmanyeswara,Rao, Jampani Madhusundana

, p. 1046 - 1048 (2007/10/02)

The synthesis of 2-butynenitrile (7a), 3-(4-methoxyphenyl)-(7b)-, 3-(4-ethoxyphenyl)-(7c)-, 3-(4-nitrophenyl)-(7d)- and 3-(3,4,5-trimethoxyphenyl)-(7e)-propynenitriles by thermal decomposition of the corresponding acylcyanomethylenetriphenylphosphoranes (6a-e) is described.The ethoxycarbonylcyanomethylenetriphenylphosphorane (6f) under the same conditions does not give the alkynenitrile.Cleavage to triphenylphosphine oxide and acetylenic nitrile is the predominant fragmentation observed in the mass spectra of all the ylids.
