54622-43-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54622-43-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,6,2 and 2 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 54622-43:
(7*5)+(6*4)+(5*6)+(4*2)+(3*2)+(2*4)+(1*3)=114
114 % 10 = 4
So 54622-43-4 is a valid CAS Registry Number.

Intramolecular cyclization of 1,3-diamino-2-hydroxypropan-N,N,ń,ń-tetrakis(methylphosphonic acid) upon phosphonomethylation of 1,3-diaminopropan-2-ol
Tsiru?nikova,Ya Bolt,Belus
, p. 1200 - 1201 (2016/02/09)
Phosphonomethylation of 1,3-diaminopropan-2-ol affords the mixture of 1,3-diamino-2-hydroxypropan-N,N,ń,ń-tetrakis(methylphosphonic acid) (1) with its cyclic ether, viz., [(6-[bis(phosphonomethyl)amino]methyl-2-hydroxy-2-oxido-1,4,2-oxazaphosphinan-4-yl)methyl]phosphonic acid (2), but not 1, as assumed earlier.
