Cyclic 1-methyl-1,2-ethanediyl acetal, also known as 1,1-dimethoxyethane or methylal, is an organic compound with the chemical formula C4H10O2. It is a cyclic acetal derived from formaldehyde and methanol, featuring a three-membered ring structure with two oxygen atoms and one carbon atom. This colorless, volatile liquid is used as a solvent and a reagent in various chemical reactions, particularly in the synthesis of pharmaceuticals and agrochemicals. It is also employed as a fuel additive and a blowing agent for foam plastics. Due to its reactivity, it is important to handle methylal with care, as it can be harmful if inhaled or ingested, and may cause irritation to the skin and eyes.

The CAS Registry Mumber 4745-16-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,4 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4745-16:
(6*4)+(5*7)+(4*4)+(3*5)+(2*1)+(1*6)=98
98 % 10 = 8
So 4745-16-8 is a valid CAS Registry Number.
