Check Digit Verification of cas no
The CAS Registry Mumber 887919-35-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,7,9,1 and 9 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 887919-35:
(8*8)+(7*8)+(6*7)+(5*9)+(4*1)+(3*9)+(2*3)+(1*5)=249
249 % 10 = 9
So 887919-35-9 is a valid CAS Registry Number.

, (2018/11/03)
The invention discloses a preparation method for bis[di-tert-butyl(4-dimethylaminophenyl)phosphine]dichloropalladium. The preparation method comprises the following steps that 1, a Grignard reagent isprepared from the raw materials of N, N-dimethyl p-haloaniline and magnesium chips; 2, the Grignard reagent is taken and cooled, then a catalyst is added for reaction, then di-tert-butylchlorophosphane is dropwise added, and heating is carried out for reaction so as to obtain di-tert-butyl-4-dimethylaminophenylphosphine; 3, the di-tert-butyl-4-dimethylaminophenylphosphine is purified; and 4, complexing bis(acetonitrile)dichloropalladium and the purified di-tert-butyl-4-dimethylaminophenylphosphine so as to obtain a target product. The preparation method has the advantages that the di-tert-butyl-4-dimethylaminophenylphosphine is purified, the high-purity di-tert-butyl-4-dimethylaminophenylphosphine is used for reacting with the bis(acetonitrile)dichloropalladium, and therefore the yield loss of the noble metal palladium is greatly reduced, the preparation cost is greatly lowered, and the method has a good practical value.
