878-03-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 878-03-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,7 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 878-03:
(5*8)+(4*7)+(3*8)+(2*0)+(1*3)=95
95 % 10 = 5
So 878-03-5 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.
