103262-85-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 103262-85-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,2,6 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 103262-85:
(8*1)+(7*0)+(6*3)+(5*2)+(4*6)+(3*2)+(2*8)+(1*5)=87
87 % 10 = 7
So 103262-85-7 is a valid CAS Registry Number.

Utilization of the inherent nucleophile for regioselective O-acylation of polyphenols via an intermolecular cooperative transesterification

A green and efficient method for regioselective O-acylation of polyphenols has been developed. The acylation can be carried out in potassium carbonate/dimethyl sulphoxide system by utilizing the ‘inherent nucleophile’ via an intermolecular cooperative transesterification under mild condition. This method shows particular advantage in regioselective acylation of polyphenols bearing 2′,4′-dihydroxyacetophenone moiety and can be extended to the synthesis of mono or multiple acetates of polyphenols without this moiety in good yields. Compared with other reported approaches, this method is endowed with atom economy and is more environment-friendly for avoiding the use of any metal-based catalysts.
