Check Digit Verification of cas no

The CAS Registry Mumber 76513-99-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,5,1 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 76513-99:
(7*7)+(6*6)+(5*5)+(4*1)+(3*3)+(2*9)+(1*9)=150
150 % 10 = 0
So 76513-99-0 is a valid CAS Registry Number.

Studies on Organic Fluorine Compounds. Part 35. Trifluoromethylation of Pyrimidine- and Purine-nucleosides with Trifluoromethyl-Copper Complex

Kobayashi, Yoshiro,Yamamoto, Kenjiro,Asai, Toyohira,Nakano, Masanori,Kumadaki, Itsumaro

, p. 2755 - 2761 (2007/10/02)

Halogenated nucleoside derivatives were trifluoromethylated using a solution of a trifluoromethyl-copper complex, which was prepared by shaking trifluoromethyl iodide and copper powder in hexamethylphosphoric triamide and filtering off the excess of copper powder.The following trifluoromethylated nucleosides were obtained in moderate to good yields: 5-trifluoromethyl-uridine, -deoxyuridine, -cytidine, -deoxycytidine, and arabinosylcytosine; 8-trifluoromethyl-adenosine, -deoxyadenosine, and -inosine; and 6-trifluoromethylribofuranosylpurine.This procedure offers simple synthesis of many trifluoromethyl compounds.
