1451210-45-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1451210-45-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,1,2,1 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1451210-45:
(9*1)+(8*4)+(7*5)+(6*1)+(5*2)+(4*1)+(3*0)+(2*4)+(1*5)=109
109 % 10 = 9
So 1451210-45-9 is a valid CAS Registry Number.

An efficient two step synthetic methodology of new 5(4)-aryl-4(5)-[3(5)-(2- hydroxyphenyl)-1H-pyrazol-5(3)-yl]-1H-1,2,3-triazole dyads was established. The reaction of (E)-2-styryl-4H-chromen-4-ones, used as building blocks, with sodium azide, gave 4(5)-a
