Trans-1-Boc-3,4-pyrrolidinedicarboxylic acid, 3-ethyl ester is a chemical compound with the molecular formula C14H23NO5. It is a derivative of pyrrolidine and is commonly used in organic synthesis as a protecting group for amines. The "Boc" group, standing for t-butoxycarbonyl, helps to protect the amine functional group from unwanted reactions during synthesis, and is removed under mild acidic conditions. The 3-ethyl ester group is also a common protecting group for carboxylic acids, and can be selectively removed under appropriate conditions. Trans-1-Boc-3,4-pyrrolidinedicarboxylic acid, 3-ethyl ester is important in the field of organic chemistry for the protection and manipulation of amine and carboxylic acid functional groups.

Check Digit Verification of cas no

The CAS Registry Mumber 252919-44-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,2,9,1 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 252919-44:
(8*2)+(7*5)+(6*2)+(5*9)+(4*1)+(3*9)+(2*4)+(1*4)=151
151 % 10 = 1
So 252919-44-1 is a valid CAS Registry Number.
