(4S)-2t-((R)-tert-butoxycarbonyl-phthalimido-methyl)-5,5-dimethyl-thiazolidine-4r-carboxylic acid is a complex organic compound with a molecular structure that features a thiazolidine ring, a carboxylic acid group, and a protected amino acid side chain. The compound is characterized by its chiral centers, with the "4S" and "R" designations indicating the specific stereochemistry at these centers. The "tert-butoxycarbonyl" (Boc) group is a common protecting group in peptide synthesis, which shields the amino group and allows for selective reactions at other sites. The "phthalimido" group is part of the structure, suggesting that (4S)-2t-((R)-tert-butoxycarbonyl-phthalimido-methyl)-5,5-dimethyl-thiazolidine-4r-carboxylic acid may be related to peptide or protein chemistry, where such groups are used to protect the amino terminus. The "5,5-dimethyl" part of the name indicates two methyl groups attached to the thiazolidine ring, which contributes to the compound's steric properties. Overall, (4S)-2t-((R)-tert-butoxycarbonyl-phthalimido-methyl)-5,5-dimethyl-thiazolidine-4r-carboxylic acid is likely used in the synthesis of more complex molecules, such as peptides or other biologically active compounds, where its specific structure and protecting groups play a crucial role in the reaction sequence.

Check Digit Verification of cas no

The CAS Registry Mumber 1056-69-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,5 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1056-69:
(6*1)+(5*0)+(4*5)+(3*6)+(2*6)+(1*9)=65
65 % 10 = 5
So 1056-69-5 is a valid CAS Registry Number.
