Check Digit Verification of cas no

The CAS Registry Mumber 127500-37-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,5,0 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 127500-37:
(8*1)+(7*2)+(6*7)+(5*5)+(4*0)+(3*0)+(2*3)+(1*7)=102
102 % 10 = 2
So 127500-37-2 is a valid CAS Registry Number.

Synthesis and reactivity of 1-substituted 2-fluoro- and 2,2-difluoroaziridines

Verniest, Guido,Colpaert, Filip,Van Hende, Eva,De Kimpe, Norbert

, p. 8569 - 8572 (2008/02/13)

(Chemical Equation Presented) A straightforward synthesis toward 2-fluorinated aziridines was developed via ring closure of β-fluorinated β-chloroamines, which were obtained via reduction of the corresponding α-fluorinated amides by borane. When 1-benzyl-2-fluoroaziridine was treated with methanol, reaction occurred at the 2-position, giving rise to N-benzyl-2,2-dimethoxyethylamine, while in the case of 1-benzyl-2,2- difluoroaziridine the 3-position was attacked, giving rise to N-benzyl-2-methoxyacetamide. These reactions point to the divergent reactive behavior of monofluoro- and difluoroaziridines.
