906377-57-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 906377-57-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,6,3,7 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 906377-57:
(8*9)+(7*0)+(6*6)+(5*3)+(4*7)+(3*7)+(2*5)+(1*7)=189
189 % 10 = 9
So 906377-57-9 is a valid CAS Registry Number.

Pummerer fragmentation vs. Pummerer rearrangement: A mechanistic analysis
Laleu, Benoit,MacHado, Marco Santarem,Lacour, Jerome
, p. 2786 - 2788 (2008/09/19)
Depending upon the nature of the substituent at the β-position of the sulfoxide moiety, a Pummerer reaction can be oriented "at will" towards Cα-H (rearrangement) or Cα-C β (fragmentation) bond cleavage. The Royal Society of Chemistry 2006.
