1,3:2,4-di-O-ethylidene-D-sorbitol is a chemical compound derived from D-sorbitol, a sugar alcohol. It is formed by the reaction of D-sorbitol with acetaldehyde, resulting in the formation of an acetal structure. 1,3:2,4-di-O-ethylidene-D-sorbitol is characterized by the presence of two ethylidene groups (-CH2-O-CH2-) at the 1,3 and 2,4 positions of the D-sorbitol molecule, which replaces the hydroxyl groups (-OH) at these positions. The resulting compound has a molecular formula of C10H20O6 and is often used as a starting material in the synthesis of various chemicals, including pharmaceuticals and other organic compounds. Its unique structure and properties make it an important intermediate in organic chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 50895-31-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,8,9 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 50895-31:
(7*5)+(6*0)+(5*8)+(4*9)+(3*5)+(2*3)+(1*1)=133
133 % 10 = 3
So 50895-31-3 is a valid CAS Registry Number.
