Check Digit Verification of cas no
The CAS Registry Mumber 18742-94-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,7,4 and 2 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 18742-94:
(7*1)+(6*8)+(5*7)+(4*4)+(3*2)+(2*9)+(1*4)=134
134 % 10 = 4
So 18742-94-4 is a valid CAS Registry Number.

Enol Ethers, XIV. Acylation of Keto Enol Ethers with Malonyl Dichloride - A New Synthesis of Phloroglucinols
Effenberger, Franz,Schoenwaelder, Karl-Heinz
, p. 3270 - 3279 (2007/10/02)
Phloroglucinols 4 and/or 4-hydroxy-2H-pyran-2-ones 5 are formed from keto enol ethers 1 and malonyl dichloride (2a) in high yields.Since the pyranones 5 can be smoothly converted into phloroglucinols, the reaction of 1 with 2a represents a new, facile synthetic route to phloroglucinols.The reaction proceeds via formation of a chloro carbonyl ketene 8 and its subsequent reaction with 1.The product ratio 4:5 is rationalized in terms of substituent effects in the enol ether substrate.
