Trimethylsilyl-α-phenylpropionat, also known as (trimethylsilyl)oxy(phenyl)propan-2-olate, is an organosilicon compound with the chemical formula C10H16O2Si. It is a colorless liquid that is soluble in organic solvents and is commonly used as a protecting group in organic synthesis, particularly for the protection of carbonyl compounds. The compound is formed by the reaction of α-phenylpropionyl chloride with trimethylsilyl alcohol, resulting in the formation of a silyl ether that masks the carbonyl group, preventing unwanted side reactions. Trimethylsilyl-α-phenylpropionat is a valuable reagent in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals due to its ability to selectively protect specific functional groups while allowing other reactions to proceed.

Check Digit Verification of cas no

The CAS Registry Mumber 40348-57-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,3,4 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 40348-57:
(7*4)+(6*0)+(5*3)+(4*4)+(3*8)+(2*5)+(1*7)=100
100 % 10 = 0
So 40348-57-0 is a valid CAS Registry Number.
