N-(4-Nitro-benzyloxycarbonyl)-N-methyl-L-valin, also known as NMB-L-Val, is a synthetic chemical compound with the molecular formula C15H18N2O6. It is a derivative of L-valine, an essential amino acid, and features a 4-nitro-benzyloxycarbonyl (NBoc) protecting group and a methyl group attached to the nitrogen atom. N-(4-Nitro-benzyloxycarbonyl)-N-methyl-L-valin is commonly used in peptide synthesis as a protected amino acid building block, where the NBoc group shields the amino group from unwanted side reactions, allowing for controlled peptide bond formation. The nitro group on the benzyl moiety provides a distinct UV absorbance, facilitating the monitoring of reactions and purification processes. NMB-L-Val is a valuable tool in the field of organic chemistry and biochemistry, particularly in the synthesis of complex peptides and proteins with controlled functional groups.

Check Digit Verification of cas no

The CAS Registry Mumber 4216-94-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,1 and 6 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4216-94:
(6*4)+(5*2)+(4*1)+(3*6)+(2*9)+(1*4)=78
78 % 10 = 8
So 4216-94-8 is a valid CAS Registry Number.
