α-Hydroxy-isobutyric acid methallyl ester, also known as α-hydroxyisobutyrate methallyl ester, is a chemical compound with the molecular formula C7H12O3. It is an ester derivative of α-hydroxyisobutyric acid, where the hydroxyl group is replaced by a methallyl group (a three-carbon chain with a double bond). This organic compound is characterized by its ability to form a cyclic ester due to the presence of both a hydroxyl group and a carbonyl group in its structure. It is used in various chemical reactions and synthesis processes, particularly in the preparation of pharmaceuticals and other organic compounds. The compound is known for its stability and reactivity, which makes it a valuable intermediate in organic synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 19444-22-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,4,4 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 19444-22:
(7*1)+(6*9)+(5*4)+(4*4)+(3*4)+(2*2)+(1*2)=115
115 % 10 = 5
So 19444-22-5 is a valid CAS Registry Number.
