224583-37-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 224583-37-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,4,5,8 and 3 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 224583-37:
(8*2)+(7*2)+(6*4)+(5*5)+(4*8)+(3*3)+(2*3)+(1*7)=133
133 % 10 = 3
So 224583-37-3 is a valid CAS Registry Number.

Synthesis of 6-N-biotinylaminohexyl isopropyl phosphorofluoridate: A potent tool for the inhibition/isolation of serine esterases and proteases
Higson, Adrian P.,Ferguson, Michael A.J.,Nikolaev, Andrei V.
, p. 407 - 409 (1999)
6-N-Biotinylaminohexyl isopropyl phosphorofluoridate 2 was prepared by treatment of the corresponding hydrogen phosphonic diester with triethylamine trihydrofluoride and iodine. The activity of the phosphorofluoridate was tested by the inhibition of achymotrypsin.
