1158-19-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1158-19-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,5 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1158-19:
(6*1)+(5*1)+(4*5)+(3*8)+(2*1)+(1*9)=66
66 % 10 = 6
So 1158-19-6 is a valid CAS Registry Number.

Solid-Phase Benzoylation of Phenols and Alcohols in Microwave Reactor: An Ecofriendly Protocol

Chakraborty, Suchandra,Saha, Ahana,Basu, Kaushik,Saha, Chandan

supporting information, p. 2331 - 2343 (2015/10/12)

An efficient solid-phase benzoylation of phenols and alcohols was developed under microwave irradiation. A stoichiometric amount of benzoyl chloride was sufficient to carry out the reaction. This benzoylation features short reaction time, good yields, and easy workup procedures. Furthermore, the scope of the reaction was extended to prepare 3,5-dinitrobenzoyl derivatives of alcohols.
