137449-19-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137449-19-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,4,4 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 137449-19:
(8*1)+(7*3)+(6*7)+(5*4)+(4*4)+(3*9)+(2*1)+(1*9)=145
145 % 10 = 5
So 137449-19-5 is a valid CAS Registry Number.

, p. 790 - 792 (2007/10/02)
1-(Substituted coumarinoxy)-3-substituted coumarinoxy/benzisoxazoloxy)-2-hydroxypropane (1-15) have been synthesised by treating substituted hydroxycoumarins and 6-hydroxy-3-methylbenzisoxazole with epichlorohydrin and found to possess PCA activities.
