Check Digit Verification of cas no
The CAS Registry Mumber 28056-54-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,0,5 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 28056-54:
(7*2)+(6*8)+(5*0)+(4*5)+(3*6)+(2*5)+(1*4)=114
114 % 10 = 4
So 28056-54-4 is a valid CAS Registry Number.

Alternative synthesis of 2-hydroxy-3,5,5-trimethylcyclopent-2-en-1-one
Chapuis, Christian,Saint-Leger, Christine
scheme or table, p. 111 - 117 (2010/04/01)
The 2-hydroxy-3,5,5-trimethylcyclopent-2-en-1-one (1) was synthesized in 42% yield by rearrangement of epoxy ketone 10 on treatment with BF3 ? Et2O under anhydrous conditions. Intermediate 10 was available from the known enone 8, either via direct epoxidation (60% H2O 2 , NaOH, MeOH; yield 50%), or via reduction to the corresponding allylic alcohol 14 (LiAlH4, THF), followed by epoxidation ([VO(acac)2], tBuOOH) and reoxidation under Swern conditions, in 37% total yield.
