Check Digit Verification of cas no

The CAS Registry Mumber 1142816-82-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,2,8,1 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1142816-82:
(9*1)+(8*1)+(7*4)+(6*2)+(5*8)+(4*1)+(3*6)+(2*8)+(1*2)=137
137 % 10 = 7
So 1142816-82-7 is a valid CAS Registry Number.

An efficient one-pot strategy for the synthesis of 4- methylene-2-thiazolidinethiones in water

Hou, Chang-Long,Wei, Mei-Hong,Chen, Li-Li,Liu, Xiao-Ling,Sheng, Shou-Ri

, p. 1561 - 1566 (2020)

A simple and efficient, one-pot strategy for the preparation of 4-methylene-2-thiazolidinethiones has been developed. This protocol involved condensation of primary amines with carbon disulfide in water to generate the dithiocarbamate salts in situ, which coupled with 2,3-dibromopropene, followed by intramolecular cyclization to the corresponding heterocycles in moderate to good yields.

Enantioselective synthesis of 3,5-disubstituted thiohydantoins and hydantoins

Chen, Yu,Su, Li,Yang, Xinying,Pan, Wenyan,Fang, Hao

, p. 9234 - 9239 (2015/11/27)

A mild method to convert optically pure amino acid thiourea and urea derivatives to thiohydantoins and hydantoins, respectively, is described. It provides an efficient way to realize enantioselective synthesis of thiohydantoins and hydantoins with good to high isolated yields and enantiomeric purities. We found that the enantiomeric purities were highly dependent on the reaction conditions including bases, solvents, and temperature.

5-Nitrofuran-2-yl derivatives: Synthesis and inhibitory activities against growing and dormant mycobacterium species

Sriram, Dharmarajan,Yogeeswari, Perumal,Dhakla, Prathiba,Senthilkumar, Palaniappan,Banerjee, Debjani,Manjashetty, Thimmappa H.

body text, p. 1152 - 1154 (2009/08/07)

Eighteen 5-nitrofuran-2-yl derivatives were prepared by reacting 5-nitro-2-furfural with various (sub)phenyl/pyridyl thiosemicarbazide using microwave irradiation. The compounds were tested for their in vitro activity against tubercular and various non-tubercular mycobacterium species in log-phase and 6-week-starved cultures. Compound N-(3,5-dibromopyridin-2-yl)-2-((5-nitrofuran-2-yl)methylene)hydrazinecarbothioamide (4r) was found to be the most potent compound (MIC: 0.22 μM) and was 3 times more active than standard isoniazid (INH) and equally active as rifampicin (RIF) in log-phase culture of Mycobacterium tuberculosis H37Rv. In starved M. tuberculosis H37Rv, 4r inhibited with MIC of 13.9 μM and was found to be 50 times more active than INH and slightly more active than RIF.
