Check Digit Verification of cas no

The CAS Registry Mumber 84817-45-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,8,1 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 84817-45:
(7*8)+(6*4)+(5*8)+(4*1)+(3*7)+(2*4)+(1*5)=158
158 % 10 = 8
So 84817-45-8 is a valid CAS Registry Number.

Generation of Nitrile Oxides via O-Tributylstannyl Aldoximes; Application to the Synthesis of Isoxazolines and Isoxazoles

Moriya, Osamu,Takenaka, Hideo,Iyoda, Masaichi,Urata, Yoshikiyo,Endo, Takeshi

, p. 413 - 418 (1994)

Nitrile oxides were generated readily by the reaction of aldoximes 1, with tert-butyl hypochlorite and bis(tributyltin) oxide.The reaction proceeded efficiently under mild conditions, in which O-stannylated aldoximes 2 are thought to be key intermediates.This reaction system was applicable to the one-pot syntheses of isoxazole derivatives 4 and 5 in the presence of dipolarophiles via a cycloaddition.
