90265-97-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90265-97-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,2,6 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90265-97:
(7*9)+(6*0)+(5*2)+(4*6)+(3*5)+(2*9)+(1*7)=137
137 % 10 = 7
So 90265-97-7 is a valid CAS Registry Number.

SYNTHESIS OF 4,5-DIHYDRO-1H-IMIDAZOLES FROM 1,5-DIHYDRO-2H-IMIDAZOLES USING 'NICKEL BORIDE'
Euerby, Melvin R.,Oldroyd, Amanda C.,Waigh, Roger D.
, p. 2871 - 2877 (2007/10/02)
In situ prepared 'nickel boride' generated from sodium borohydride and nickel (II) chloride cleanly transforms 1,5-dihydro-2H-imidazoles into 4,5-dihydro-1H-imidazoles in high yields by a double bond migration.
