500899-82-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 500899-82-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,0,8,9 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 500899-82:
(8*5)+(7*0)+(6*0)+(5*8)+(4*9)+(3*9)+(2*8)+(1*2)=161
161 % 10 = 1
So 500899-82-1 is a valid CAS Registry Number.

Synthesis of N,N-diaryl-N′,N′-1,4- phenylenedi(oxyacetyl)dithioureas and corresponding diureas
Wang, Xicun,Li, Zheng,Guo, Zongsheng
, p. 3373 - 3381 (2007/10/03)
N,N-Diaryl-N′,N′-1,4-phenylenedi(oxyacetyl)-dithioureas (3a-1) are synthesized under solid-liquid phase transfer catalysis. Meanwhile, the corresponding diureas of 3a-1, N,N-Diaryl-N′,N′-1,4-phenylenedi(oxyacetyl)-diureas (4a-1), are further synthesized b
