18330-94-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 18330-94-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,3,3 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 18330-94:
(7*1)+(6*8)+(5*3)+(4*3)+(3*0)+(2*9)+(1*4)=104
104 % 10 = 4
So 18330-94-4 is a valid CAS Registry Number.

High Turnover Pd/C Catalyst for Nitro Group Reductions in Water. One-Pot Sequences and Syntheses of Pharmaceutical Intermediates

Gallou, Fabrice,Li, Xiaohan,Lipshutz, Bruce H.,Takale, Balaram S.,Thakore, Ruchita R.

supporting information, p. 8114 - 8118 (2021/10/25)

Commercially available Pd/C can be used as a catalyst for nitro group reductions with only 0.4 mol % Pd loading. The reaction can be performed using either silane as a transfer hydrogenating agent or simply a hydrogen balloon (μ1 atm pressure). With this technology, a series of nitro compounds was reduced to the desired amines in high chemical yields. Both the catalyst and surfactant were recycled several times without loss of reactivity.
