53501-22-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 53501-22-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,5,0 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 53501-22:
(7*5)+(6*3)+(5*5)+(4*0)+(3*1)+(2*2)+(1*2)=87
87 % 10 = 7
So 53501-22-7 is a valid CAS Registry Number.

Synthesis and biological activity of N-aroyl-N′-substituted thiourea derivatives
Zhang,Wei,Gao
, p. 3099 - 3105 (2007/10/03)
A series of N-aroyl-N′-substituted thiourea derivatives have been prepared in good to excellent yields under the condition of solid-liquid phase transfer catalysis using polyethylene glycol-400(PEG-400) as the catalyst. The products have been characterize
