Check Digit Verification of cas no

The CAS Registry Mumber 68883-09-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,8,8 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 68883-09:
(7*6)+(6*8)+(5*8)+(4*8)+(3*3)+(2*0)+(1*9)=180
180 % 10 = 0
So 68883-09-0 is a valid CAS Registry Number.

Highly efficient protection of alcohols as trityl ethers under solvent-free conditions, and recovery catalyzed by reusable nanoporous MCM-41-SO3H

Gholamzadeh, Zeynab,Naimi-Jamal, Mohammad Reza,Maleki, Ali

, p. 994 - 1001 (2015/01/09)

An efficient method was developed for the protection of alcohols as trityl ethers using triphenylmethanol in the presence of nanoporous MCM-41-SO3H as a heterogeneous catalyst under solvent-free ball-milling at room temperature. Low catalyst loading, high efficiency, reusability are among the advantages of this new solvent-free and environmentally friendly method. The deprotection of the produced trityl ethers was also efficiently achieved using the same catalyst in wet acetonitrile.

N, N′ - Ditritylurea and analogs as hosts in crystalline clathrate complexes: Synthesis and selectivity studies

Ng, Kwok-Keung Daniel,Hart, Harold

, p. 7883 - 7906 (2007/10/02)

Of 38 hosts, most of them new, designed on the 'wheel-and-axle' model, 24 formed clathrate complexes with small molecules; 95 new host/guest combinations are described (Table 6). Selectivity studies (Table 7) show, in some instances, substantial discrimin
