147152-22-5 Usage
General Description
(+)-Hydroxyzine is a medication that is primarily used to treat anxiety and tension. It works by blocking the effects of histamine, which is a natural substance in the body that is involved in allergic reactions. By blocking histamine, (+)-Hydroxyzine can help alleviate symptoms such as itching, hives, and sneezing. It is also used as a sedative to treat anxiety and tension, and can be prescribed to help manage nausea and vomiting. This medication is available in oral and injectable formulations, and should be used with caution in patients with a history of glaucoma, urinary retention, or with certain medical conditions such as heart disease. Additionally, (+)-Hydroxyzine may cause drowsiness and should be used with caution when driving or operating heavy machinery.
Check Digit Verification of cas no
The CAS Registry Mumber 147152-22-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,1,5 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 147152-22:
(8*1)+(7*4)+(6*7)+(5*1)+(4*5)+(3*2)+(2*2)+(1*2)=115
115 % 10 = 5
So 147152-22-5 is a valid CAS Registry Number.

A facile iridium/graphene-catalyzed methodology providing an efficient synthetic route for C-N bond formation is reported. This catalyst can directly promote the formation of C-N bonds, without pre-activation steps, and without solvents, alkalis and other additives. This protocol provides a direct N-alkylation of amines using a variety of primary and secondary alcohols with good selectivity and excellent yields. Charmingly, the use of diols resulted in intermolecular cyclization of amines, and such products are privileged structures in biologically active compounds. Two examples illustrate the advantages of this catalyst in organic synthesis: the tandem catalysis to synthesize hydroxyzine, and the intermolecular cyclization to synthesize cyclizine. Water is the only by-product, which makes this catalytic process sustainable and environmentally friendly. This journal is
