145090-49-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145090-49-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,0,9 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 145090-49:
(8*1)+(7*4)+(6*5)+(5*0)+(4*9)+(3*0)+(2*4)+(1*9)=119
119 % 10 = 9
So 145090-49-9 is a valid CAS Registry Number.

At 0 deg C, 1,3-thiazoles 1 and 2-diazopropane in pentane or MeOH undergo a smooth 1,3-dipolar cycloaddition to give spirocyclic 2,4-dihydro-1,3,4-thiadiazoles 6 (Scheme 3).Elimination of N2 occurs already at 20 deg C, yielding spirocyclic thiiranes 7.At
