423735-21-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 423735-21-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,3,7,3 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 423735-21:
(8*4)+(7*2)+(6*3)+(5*7)+(4*3)+(3*5)+(2*2)+(1*1)=131
131 % 10 = 1
So 423735-21-1 is a valid CAS Registry Number.

Isolation of intermediates in the synthesis of thieno[2,3-d]pyrimidine-2, 4(1H,3H)-diones using microwave irradiation

Davoodnia,Zare-Bidaki,Eshghi

experimental part, p. 2968 - 2973 (2009/09/06)

A simple and fast method for the isolation of intermediates in the synthesis of 3-arylthieno[2,3-d]pyrimidine-2,4(1H,3H)-diones has been developed by microwave-assisted condensation of ethyl 2-amino-4,5-dimethylthiophene-3- carboxylate with aryl isocyanat
