Methanethione, bis(4-nitrophenyl)-, also known as 4-nitrophenyl methanethiosulfonate or NPM, is a chemical compound with the molecular formula C8H6N2O6S2. It is a yellow crystalline solid that is soluble in organic solvents such as ethanol and acetone. NPM is commonly used as a reagent in organic synthesis, particularly in the preparation of various sulfur-containing compounds. It is also employed as a protecting group in peptide synthesis, where it can be used to protect thiol groups during the formation of disulfide bonds. Additionally, NPM has been studied for its potential applications in the development of new drugs and agrochemicals. Due to its reactivity and potential health hazards, it is important to handle NPM with care and proper safety measures.

Check Digit Verification of cas no

The CAS Registry Mumber 1154-91-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,5 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1154-91:
(6*1)+(5*1)+(4*5)+(3*4)+(2*9)+(1*1)=62
62 % 10 = 2
So 1154-91-2 is a valid CAS Registry Number.
