Check Digit Verification of cas no
The CAS Registry Mumber 36042-94-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,0,4 and 2 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 36042-94:
(7*3)+(6*6)+(5*0)+(4*4)+(3*2)+(2*9)+(1*4)=101
101 % 10 = 1
So 36042-94-1 is a valid CAS Registry Number.

Paragraph 0016-0017, (2018/06/15)
The invention discloses a method for preparing a diarylphosphochlorine compound and belongs to the field of organic synthesis. The method is as follows: the diarylphosphochlorine compound is preparedby reaction of triarylphosphine as a starting material with phosphorus trichloride in the presence of zinc trifluoromethanesulfonate as a catalyst and distillation. Compared with the prior art, the method has the advantages of high reaction yield and simple post-treatment, is particularly suitable for preparation of the diarylphosphochlorine compound with a substituent, and is more suitable for industrial production. The obtained diarylphosphochlorine compound can be used as a ligand for synthesizing metal catalysts, and is applied to the fields such as organic photoelectric materials and medicines.
