β-(p-Trimethylsilylphenyl)-propionic acid, also known as β-(4-Trimethylsilylphenyl)propionic acid, is an organosilicon compound with the chemical formula C12H18O2Si. It features a propionic acid backbone, with a trimethylsilyl group (Si(CH3)3) attached to the para position of a phenyl ring. β-(p-Trimethylsilylphenyl)-propionsaeure is often used in organic synthesis, particularly in the preparation of various pharmaceuticals and agrochemicals, due to its ability to act as a protecting group for carboxylic acids. The trimethylsilyl group can be easily introduced and removed under mild conditions, making it a valuable tool in the synthesis of complex molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 20119-67-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,1,1 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 20119-67:
(7*2)+(6*0)+(5*1)+(4*1)+(3*9)+(2*6)+(1*7)=69
69 % 10 = 9
So 20119-67-9 is a valid CAS Registry Number.
