1-p-Tolyl-1,3-propandiol-diacetat, also known as 1-(4-methylphenyl)-1,3-propanediol diacetate, is an organic compound with the chemical formula C13H16O4. It is a colorless to pale yellow liquid with a molecular weight of 236.26 g/mol. 1-p-Tolyl-1,3-propandiol-diacetat is derived from 1,3-propanediol, a three-carbon diol, and p-tolyl, a methylated phenyl group. The diacetate functional group is formed by the esterification of the two hydroxyl groups in 1,3-propanediol with acetic acid. 1-p-Tolyl-1,3-propandiol-diacetat is used as a synthetic intermediate in the production of various chemicals, pharmaceuticals, and fragrances. It is characterized by its unique chemical structure, which combines the properties of the 1,3-propanediol backbone with the aromatic nature of the p-tolyl group, making it a versatile building block in organic synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 34688-54-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,6,8 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 34688-54:
(7*3)+(6*4)+(5*6)+(4*8)+(3*8)+(2*5)+(1*4)=145
145 % 10 = 5
So 34688-54-5 is a valid CAS Registry Number.
