4513-75-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4513-75-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,1 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4513-75:
(6*4)+(5*5)+(4*1)+(3*3)+(2*7)+(1*5)=81
81 % 10 = 1
So 4513-75-1 is a valid CAS Registry Number.

Silver(I) ion-mediated desulfurization-condensation of carbon disulfide with some hydroxyl compounds

Shibuya, Isao,Gama, Yasuo,Shimizu, Masao

, p. 461 - 464 (1998)

The title reaction with ethanol and phenol gave tetraethyl and tetraphenyl orthocarbonate, respectively, in good yields. Diols, such as benzene-1,2-dimethanol, wieso-hydrobenzoin, and cathecol, afforded spiro orthocarbonic acid esters. In the same manner, 2-anilinoethanol, N-methylanthranilic acid, and salicylic acid led to some novel spirobicycles.

Method for making diaryl carbonate

-

, (2008/06/13)

Diaryl carbonate is prepared by hydrolysis of a tetraaryl orthocarbonate in the presence of an acid catalyst. The tetraaryl orthocarbonate is synthesized by a reaction between carbon disulfide and a cuprous phenate; the cuprous phenate can be made from cuprous chloride and the corresponding alkali metal phenate. The process may be integrated with recycle of by-products.
