30518-54-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 30518-54-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,5,1 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 30518-54:
(7*3)+(6*0)+(5*5)+(4*1)+(3*8)+(2*5)+(1*4)=88
88 % 10 = 8
So 30518-54-8 is a valid CAS Registry Number.

THERMAL BEHAVIOUR OF ARYL γ-HALOPROPARGYL ETHERS

Ariamala, G.,Balasubramanian, K. K.

, p. 309 - 318 (2007/10/02)

A systematic study of the behaviour of aryl γ-halopropargyl ethers under thermal condition was undertaken.Aryl γ-bromopropargyl ethers 2 underwent unique transformation in N,N-diethylaniline (215 deg C, 6 h) giving rise to a mixture of products 3,4 and 5,whereas, under similar conditions aryl γ-chloropropargyl ethers 8, afforded 4-chlorochromenes, 9.A remarkable substituent and solvent effect has been observed in the thermolysis of these aryl γ-bromo and γ-chloropropargyl ethers, rendering this transformation as a method for the synthesis of a number of substituted 4-bromochromenes 3, 4-chlorochromenes 9 and chroman-4-ones 7.In contrast, solution thermolysis of aryl γ-iodopropargyl ether 11 afforded aryl propargyl ether 1 as the major product.
