Check Digit Verification of cas no

The CAS Registry Mumber 431075-50-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,1,0,7 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 431075-50:
(8*4)+(7*3)+(6*1)+(5*0)+(4*7)+(3*5)+(2*5)+(1*0)=112
112 % 10 = 2
So 431075-50-2 is a valid CAS Registry Number.

Synthesis and insecticidal activity of new substituted N-aryl-N′-benzoylthiourea compounds

Xu, Xiaoyong,Qian, Xuhong,Li, Zhong,Huang, Qingchun,Chen, Gang

, p. 51 - 54 (2003)

Eight new substituted N -aryl- N ′-benzoylthioureas have been synthesised by a facile and mild method with high yield at room temperature. The structures of all compounds were confirmed by 1H NMR, mass and high resolution mass spectroscopy. The

Synthesis and antibacterial activity of new N-acyl-N′-(3-chloro-4- fluorophenyl)thioureas

Khazi,Koti,Chadha, Monica V.,Mahajanshetti

, p. 761 - 763 (2007/10/03)

A new series of N-acyl-N′-(3-chloro-4-fluorophenyl)thioureas have been prepared in excellent yield by the reaction of acylthiocyanates and 3-chloro-4-fluoroaniline under solid-liquid phase transfer catalysis using PEG-400. All synthesised compounds were screened against Escherichia coli and Staphylococcus aureus in DMF for evaluating their antibacterial activity. 2d, 2e, 2f and 2g showed good activity at 50 μg/ml dilution.
