1321620-08-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1321620-08-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,1,6,2 and 0 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1321620-08:
(9*1)+(8*3)+(7*2)+(6*1)+(5*6)+(4*2)+(3*0)+(2*0)+(1*8)=99
99 % 10 = 9
So 1321620-08-9 is a valid CAS Registry Number.

Efficient one-pot synthesis of 4-aroyl-2-pyrones: Nucleophilic addition of active methylene groups to 1,2-diaroylacetylenes

Shankar, Ravi,Shukla, Harsha,Singh, Uma Sharan,Thakur, Vinay,Hajela

, p. 2738 - 2746 (2011)

An efficient synthesis of 3,6-disubstituted-4-aroyl-2-pyrones in a single-stepreaction through Michael addition of 1,2-diaroylacetylenes with active methylene compounds in the presence of NaH in dimethylsulfoxide at room temperature is reported. The structures have been confirmed by spectral data analyses. Taylor & Francis Group, LLC.
