Check Digit Verification of cas no

The CAS Registry Mumber 847240-15-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,7,2,4 and 0 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 847240-15:
(8*8)+(7*4)+(6*7)+(5*2)+(4*4)+(3*0)+(2*1)+(1*5)=167
167 % 10 = 7
So 847240-15-7 is a valid CAS Registry Number.

Efficient synthesis of piperazinediones using potassium iodide catalysis in aqueous media

Wen, Yong-Hong,Chen, Xiao-Na,Wen, Hui-Ling,Tang, Xiao-Fang

, p. 732 - 736 (2012/06/01)

A simple and efficient synthetic approach to 1,4-disubstituted piperazine-2,5-diones was developed. A series of symmetrical 1,4-disubstituted piperazine-2,5-diones was prepared from chloroacetamides using potassium iodide catalysis in acetone/water. The structures of two products were confirmed by single crystal X-ray diffraction analysis.
