Check Digit Verification of cas no
The CAS Registry Mumber 1124-35-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,2 and 4 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1124-35:
(6*1)+(5*1)+(4*2)+(3*4)+(2*3)+(1*5)=42
42 % 10 = 2
So 1124-35-2 is a valid CAS Registry Number.

Acylations des cetones α-β-ethyleniques catalysees par les acides sulfoniques : synthese concomitante de sels de pyrylium et de dihydro-2,3-pyrones-4
Graindorge, Herve,Roussel, Christian
, p. 454 - 458 (2007/10/02)
The acylation of α,β-ethylenic ketones by carboxylic acid anhydrides catalyzed by sulfonic acids lead to the expected unsymmetrical pyrylium salts. 2,3-Dihydro-pyran-4-ones are also formed.The respective yields depend upon the alkyl substituents of the starting material.
