53948-14-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 53948-14-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,9,4 and 8 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 53948-14:
(7*5)+(6*3)+(5*9)+(4*4)+(3*8)+(2*1)+(1*4)=144
144 % 10 = 4
So 53948-14-4 is a valid CAS Registry Number.

Sulfonium salts as prenyl, geranyl, and isolavandulyl transfer agents towards benzoylphloroglucinol derivatives

Brajeul, Solenn,Delpech, Bernard,Marazano, Christian

, p. 5597 - 5600 (2007)

In search for new methods aiming biomimetic synthesis of polyprenylated acylphloroglucinols (PPAPs), we now report the results of an evaluation of sulfonium salts as prenyl, geranyl, and isolavandulyl transfer agents towards benzoylphloroglucinol derivatives, in neutral conditions. As a result, conditions were found for rather efficient C-prenylation of these compounds. The corresponding trimethyl ether gave the best results, but the reaction was accompanied by a deacylation process. Geranyl transfer was also observed, but in low yield, and, interestingly, an isolavandulyl group could be introduced with an appreciable yield.
