159505-46-1 Usage
General Description
H-Tyr(Tos)-OH, also known as O-Tosyl-L-tyrosine or Tyrosine O-sulfonic Acid, is a chemical compound that is widely used in the field of peptide synthesis. It is often utilized as an intermediate for pharmaceuticals and other bio-chemicals. The compound has a molecular formula of C16H19NO6S and is soluble in water. The 'Tos' in H-Tyr(Tos)-OH refers to the tosyl group (CH3C6H4SO2), which acts as a protecting group for the tyrosine amino acid during peptide synthesis. The 'OH' depicts the presence of a hydroxyl group in the compound. It is usually kept at -20°C storage temperature. The compound should be handled carefully as it may cause skin and eye irritation.
Check Digit Verification of cas no
The CAS Registry Mumber 159505-46-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,5,0 and 5 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 159505-46:
(8*1)+(7*5)+(6*9)+(5*5)+(4*0)+(3*5)+(2*4)+(1*6)=151
151 % 10 = 1
So 159505-46-1 is a valid CAS Registry Number.
