Check Digit Verification of cas no

The CAS Registry Mumber 135264-86-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,2,6 and 4 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 135264-86:
(8*1)+(7*3)+(6*5)+(5*2)+(4*6)+(3*4)+(2*8)+(1*6)=127
127 % 10 = 7
So 135264-86-7 is a valid CAS Registry Number.

Nucleoside Analogues. Part 11. The Acylation of N-(ω-Aminoalkyl)uracil and a Bicyclic Isomer

McCormick, Joan E.,McElhinney, R. Stanley,McMurry, T. Brian H.

, p. 1216 - 1239 (2007/10/02)

The relative reactivity of the amino group and of pyrimidine N1 and N3 in N-(ω-aminoalkyl)uracils has been investigated using a variety of acylating agents.Bis(2,4,5-trichlorophenyl) carbonate, now readily available from bis(trichloromethyl) carbonate, proved a very useful selective reagent.The bicyclic isomer formed from an N1-substituted compound by intramolecular addition was also studied and afforded novel products from 2,4,5-trichlorophenyl N-(2-chloroethyl)-N-nitrosocarbamate, a standard reagent for producing N-nitrosoureas.
