Check Digit Verification of cas no
The CAS Registry Mumber 4168-73-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,6 and 8 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4168-73:
(6*4)+(5*1)+(4*6)+(3*8)+(2*7)+(1*3)=94
94 % 10 = 4
So 4168-73-4 is a valid CAS Registry Number.

Paragraph 0015, (2016/12/16)
The invention discloses a synthesis method of trihexylphosphine, belonging to the field of compound preparation. The synthesis method comprises the following steps: firstly reacting chlorohexane and magnesium chips under the protection of nitrogen gas in a mixed solvent of toluene and tetrahydrofuran by taking iodine granules as an initiator so as to obtain hexyl magnesium chloride; and without purification, cooling the hexyl magnesium chloride, directly adding phosphorus trichloride to the hexyl magnesium chloride, stirring for reacting at low temperature, and after the reaction, directly carrying out reduced pressure distillation to obtain the trihexylphosphine product. The purity of the trihexylphosphine product is more than 99%, and the yield of the trihexylphosphine product is 92.6%; and the solvent used in the synthesis method is easy to recycle.
