Check Digit Verification of cas no

The CAS Registry Mumber 18827-14-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,8,2 and 7 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 18827-14:
(7*1)+(6*8)+(5*8)+(4*2)+(3*7)+(2*1)+(1*4)=130
130 % 10 = 0
So 18827-14-0 is a valid CAS Registry Number.

Alkylation, Acylation and Silylation of Azoles

Begtrup, Mikael,Larsen, Peter

, p. 1050 - 1057 (2007/10/02)

Performing alkylation, acylation and silylation reactions in separate deprotonation and nucleophilic displacement steps allows for better control of reaction conditions and facilitates problem handling in these processes.In the alkylation of azoles the alkylating agents and solvents possess individual reaction capabilities which seem to be approximately additive.Monoalkylation occurs if the sum of the normalized reaction potentials is equal or larger than the pKa value of the azole.Dialkylation is avoided by keeping the sum of the normalized reaction potentials below the pKa value of the alkylazole.The applicability of these principles is demonstrated by the development of effective procedures for the methylation, benzylation, acetylation, methoxycarbonylation and trimethylsilylation of azoles.
