1144041-52-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1144041-52-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,4,0,4 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1144041-52:
(9*1)+(8*1)+(7*4)+(6*4)+(5*0)+(4*4)+(3*1)+(2*5)+(1*2)=100
100 % 10 = 0
So 1144041-52-0 is a valid CAS Registry Number.

1,3-Dipolar cycloaddition of perfluoroalkyl ethyle azides 1 with isocyanates 2 afforded 1-perfluoroalkyl-4-(n-Bu, phenyl or mesitylsulfonyl) tetrazol-5-ones 3 in good yields. The use of perfluoroalkyl ethyl azides extends the reaction to the less reactive
