Check Digit Verification of cas no

The CAS Registry Mumber 86958-61-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,9,5 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 86958-61:
(7*8)+(6*6)+(5*9)+(4*5)+(3*8)+(2*6)+(1*1)=194
194 % 10 = 4
So 86958-61-4 is a valid CAS Registry Number.

Selective N1-alkylation of pyrimidine bases via radical (S(RN)1) mechanism

Benhida,Gharbaoui,Lechevallier,Beugelmans

, p. 1169 - 1177 (1994)

Under photostimulated S(RN)1 conditions the cytosine nitranion behaves as a nucleophile toward the carbon radical generated from gem halonitro, or gem dinitroalcane derivatives to give regiospecifically the N-1 alkyled cytosine compound which is representative of a new series of cytosine acyclonucleosides. Uracile and its 5-fluoro or 5-nitro analogs fail to react and thymine gives an unexpected disubstituted S(RN)1 product whose formation is discussed.
