S-Benzoyl-thiomilchs?ure-trimethylsilylester, also known as S-benzoylthio-2-methylpropionic acid trimethylsilyl ester, is a chemical compound with the molecular formula C13H21O2SSi. It is a derivative of S-benzoylthio-2-methylpropionic acid, where the carboxylic acid group is protected by a trimethylsilyl (TMS) group. S-Benzoyl-thiomilchsaeure-trimethylsilylester is commonly used in organic synthesis, particularly in the protection of carboxylic acids, as the TMS group can be easily removed under mild conditions to regenerate the parent acid. The compound is also utilized in the synthesis of various pharmaceuticals and agrochemicals, where the S-benzoyl group serves as a temporary protecting group for thiols. Its stability and reactivity make it a valuable intermediate in the preparation of complex organic molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 6398-70-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,9 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6398-70:
(6*6)+(5*3)+(4*9)+(3*8)+(2*7)+(1*0)=125
125 % 10 = 5
So 6398-70-5 is a valid CAS Registry Number.
