Check Digit Verification of cas no

The CAS Registry Mumber 31657-22-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,6,5 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 31657-22:
(7*3)+(6*1)+(5*6)+(4*5)+(3*7)+(2*2)+(1*2)=104
104 % 10 = 4
So 31657-22-4 is a valid CAS Registry Number.

2-Phenyl-5,6-dihydro-2H-thieno[3,2-c]pyrazol-3-ol derivatives as new inhibitors of bacterial cell wall biosynthesis

Li, Zhong,Francisco, Gerardo D.,Hu, William,Labthavikul, Pornpen,Petersen, Peter J.,Severin, Anatoly,Singh, Guy,Yang, Youjun,Rasmussen, Beth A.,Lin, Yang-I,Skotnicki, Jerauld S.,Mansour, Tarek S.

, p. 2591 - 2594 (2007/10/03)

Twenty-five 2-phenyl-5,6-dihydro-2H-thieno[3,2-c]pyrazol-3-ol derivatives were synthesized for evaluation as new inhibitors of bacterial cell wall biosynthesis. Many of them demonstrated good inhibitory activity against Staphylococcus aureus MurB, MurC and MurD enzymes in vitro and antimicrobial activity against gram-positive bacteria including MRSA, VRE and PRSP. However, when they were tested in the presence of 4% bovine serum albumin, the MIC values increased to greater than 128 μg/mL against PRSP. None of the compounds demonstrated activity against gram-negative bacteria at MIC 32 μg/mL.
