Check Digit Verification of cas no
The CAS Registry Mumber 124455-54-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,4,5 and 5 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 124455-54:
(8*1)+(7*2)+(6*4)+(5*4)+(4*5)+(3*5)+(2*5)+(1*4)=115
115 % 10 = 5
So 124455-54-5 is a valid CAS Registry Number.

Addition-Rearrangement Reactions of N-(Arylsulphonyloxy)amines and 3,4-Dihydro-2H-pyran
Hoffman, Robert V.,Salvador, James M.
, p. 1375 - 1380 (2007/10/02)
A series of N-alkyl-O-(arylsulphonyl)hydroxylamines (NSA) was treated with 3,4-dihydro-2H-pyran (DHP).Acid-catalysed addition to the double bond followed by cationic rearrangement gave cyclic imidates from hydride migration (major) and ring expansion (min
