Check Digit Verification of cas no

The CAS Registry Mumber 2590-84-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,9 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2590-84:
(6*2)+(5*5)+(4*9)+(3*0)+(2*8)+(1*4)=93
93 % 10 = 3
So 2590-84-3 is a valid CAS Registry Number.

Steric effect in alkylation reactions by N-alkyl-N-nitrosoureas: A kinetic approach

Manso,Perez-Prior,Garcia-Santos,Calle,Casado

body text, p. 932 - 938 (2009/10/26)

The alkylation reactions of 4-(p-nitrobenzyl)pyridine (NBP), a trap for alkylating agents with nucleophilic characteristics similar to DNA base by five N-alkyl-N-nitrosoureas (methyl-, ethyl-, propyl-, butyl-, and allylnitrosourea) were investigated in 7.3 (v/v) water/dioxane medium in the 5.0-6.5 pH range. Decomposition of alkylnitrosoureas (ANU) gives rise to alkyldiazonium ions that yield NBP-R adducts directly or through carbocations in certain instances. The NBP alkylation rate constants by these species were determined. The following sequence of alkylating potential was found: methyl- > ethyl- > allyl- > propyl- > butyl group. Application of Ingold-Taft correlation analysis to the kinetic results revealed that the NBP alkylation reactions occur mainly through steric control. The values of the molar absorption coefficients of the NBP-R adducts also reveal the determinant influence of a steric effect in the formation of alkylation adducts. The kinetic results are consistent with the biological activity of ANU. Copyright
