It is a phosphorothioate compound with a molecular formula of C14H15O2PS2 and a molecular weight of 308.34 g/mol. O,O-bis(methylphenyl) hydrogen dithiophosphate is known for its ability to protect metal surfaces from corrosion and wear by forming a protective film. It is also used in the automotive and industrial sectors to improve the performance and longevity of machinery and equipment. However, it is important to handle and store this chemical with care due to its potential hazards to human health and the environment.Check Digit Verification of cas no
The CAS Registry Mumber 27157-94-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,1,5 and 7 respectively; the second part has 2 digits, 9 and 4 respectively.Calculate Digit Verification of CAS Registry Number 27157-94:
(7*2)+(6*7)+(5*1)+(4*5)+(3*7)+(2*9)+(1*4)=124
124 % 10 = 4
So 27157-94-4 is a valid CAS Registry Number.
