Check Digit Verification of cas no

The CAS Registry Mumber 149380-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,3,8 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 149380-49:
(8*1)+(7*4)+(6*9)+(5*3)+(4*8)+(3*0)+(2*4)+(1*9)=154
154 % 10 = 4
So 149380-49-4 is a valid CAS Registry Number.

1,3-Rearrangement of allylic sulphones: Rearrangement-cyclisation of allylic 4-pentenyl sulphones

Phillips, Eifion D.,Whitham, Gordon H.

, p. 2537 - 2540 (2007/10/02)

Allylic alkyl sulphones CH2:CHC(Me)2SO2R (R=Me, Et, iPr, tBu, CH2SiMe3, CH2CH2SiMe3, and CH2CH(OH)Me underwent 1,3-rearrangement on treatment with benzoyl peroxide in tBuOH. 1,3-Rearrangement did not occur in cases (R=CH2Ph, CH2COMe) where the intermediate sulphonyl radical RSO2· could undergo loss of sulphur dioxide to form a resonance-stabilised alkyl radical. Allylic 4-pentenyl sulphones undergo rearrangement with accompanying cyclisation of the intermediate radical, this process is more efficient if the allylic sulphone bears an electron withdrawing group at the β-position.
