1092557-12-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1092557-12-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,2,5,5 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1092557-12:
(9*1)+(8*0)+(7*9)+(6*2)+(5*5)+(4*5)+(3*7)+(2*1)+(1*2)=154
154 % 10 = 4
So 1092557-12-4 is a valid CAS Registry Number.

Ruthenium-catalyzed cycloaddition of nitrile oxides and alkynes: Practical synthesis of isoxazoles
Grecian, Scott,Fokin, Valery V.
, p. 8285 - 8287 (2008)
(Chemical Equation Presented) 3,4-Disubstituted and 3,4,5-trisubstituted isoxazoles have been formed from alkynes and nitrile oxides in a ruthenium(II)-catalyzed process (see scheme; cod=cycloocta-l,5-diene, Cp=C5Me5). These reaction
