(3R,5S,6R)-3-Amino-5,7-bis-benzyloxy-6-hydroxy-heptanoic acid is a complex organic compound with a molecular formula of C21H27NO5. It is a chiral molecule, meaning it has a non-superimposable mirror image, and it is characterized by its specific stereochemistry at three chiral centers (3R, 5S, and 6R). The compound features an amino group at the 3-position, two benzyloxy groups at the 5 and 7 positions, and a hydroxy group at the 6-position. This structure is significant in the field of organic chemistry and pharmaceuticals, as it can be a precursor or a building block for the synthesis of more complex molecules, such as peptides and other bioactive compounds. The benzyloxy groups are protective groups that can be removed under certain conditions to reveal the free hydroxyl groups, which is a common strategy in organic synthesis to control the reactivity of functional groups.

Check Digit Verification of cas no

The CAS Registry Mumber 85657-41-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,6,5 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 85657-41:
(7*8)+(6*5)+(5*6)+(4*5)+(3*7)+(2*4)+(1*1)=166
166 % 10 = 6
So 85657-41-6 is a valid CAS Registry Number.
