Check Digit Verification of cas no

The CAS Registry Mumber 173201-54-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,2,0 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 173201-54:
(8*1)+(7*7)+(6*3)+(5*2)+(4*0)+(3*1)+(2*5)+(1*4)=102
102 % 10 = 2
So 173201-54-2 is a valid CAS Registry Number.

Synthesis of lipophilic 3,4-disubstituted 2,5-dihydro-2,2,5,5-tetramethyl-1H-pyrrol-1-yloxyl radicals

Kalai,Baracz,Jerkovich,Hankovszky,Hideg

, p. 1278 - 1282 (2007/10/02)

The Grignard reaction of the esters 2a, b with octylmagnesium bromide proceeds through an allylic rearrangement to give the 3-methylene-4-octyl radical 3. Bromination of its O-acetyl derivative 5 gives allylic bromides 6 and 7 as key intermediates toward lipophilic spin labels.
