α-T-Benzaldehyd-diaethylacetal, also known as 1,1-diethoxy-3-phenylpropane, is an organic compound with the chemical formula C11H18O2. It is a colorless liquid that is soluble in most organic solvents. This acetal derivative is formed by the reaction of benzaldehyde with two equivalents of ethylene glycol and a catalytic amount of acid. It is used as a protecting group for aldehydes in organic synthesis, as it can be selectively removed under mild acidic conditions to regenerate the parent aldehyde. α-T-Benzaldehyd-diaethylacetal is also employed as a fragrance ingredient and a chemical intermediate in the production of various pharmaceuticals and agrochemicals.

Check Digit Verification of cas no

The CAS Registry Mumber 95172-99-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,1,7 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 95172-99:
(7*9)+(6*5)+(5*1)+(4*7)+(3*2)+(2*9)+(1*9)=159
159 % 10 = 9
So 95172-99-9 is a valid CAS Registry Number.
