Check Digit Verification of cas no
The CAS Registry Mumber 42542-01-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,5,4 and 2 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 42542-01:
(7*4)+(6*2)+(5*5)+(4*4)+(3*2)+(2*0)+(1*1)=88
88 % 10 = 8
So 42542-01-8 is a valid CAS Registry Number.

Novel molecular rearrangements of 4-hydroxy-2-cyclopentenones
novak,Szantay,Meisel,Aszodi,Szabo,fekete
, p. 435 - 450 (2007/10/02)
Novel rearrangements of hydroxycyclopentenone derivatives 1 and 24 to 7,9,11 and 31,33,35 are reported. The stereochemistry of the rearrangement is interpreted as the result of synchronous enolate induced [1.5]-sigmatropic rearrangement and stepwise addition-elimination process. Preparation of the various substrates and structural elucidation of new products are also described.
