21232-74-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21232-74-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,3 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21232-74:
(7*2)+(6*1)+(5*2)+(4*3)+(3*2)+(2*7)+(1*4)=66
66 % 10 = 6
So 21232-74-6 is a valid CAS Registry Number.

Radical Rearrangements of 2-O-(Diphenoxyphosphoryl)glycosyl Bromides
Koch, Andreas,Giese, Bernd
, p. 1687 - 1701 (2007/10/02)
A variety of 2-deoxy-1-O-diphenoxyphosphoryl-hexopyranoses were generated in situ by a radical 2->1 migration of the phosphate group.The structures of the reactive rearrangement products were fully elucidated by NMR spectroscopy.Rate constants for this ne
