Check Digit Verification of cas no

The CAS Registry Mumber 136853-30-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,8,5 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 136853-30:
(8*1)+(7*3)+(6*6)+(5*8)+(4*5)+(3*3)+(2*3)+(1*0)=140
140 % 10 = 0
So 136853-30-0 is a valid CAS Registry Number.

Lewis acid catalysed rearrangement of 7,11-epoxyisogermacrone. Formation of a new carbon skeleton

St. Enev, Valentin,Tsankova, Elena T.

, p. 6399 - 6406 (1991)

The fluorohydrin 8 has been found to be the main product of the reaction of 7,11-epoxyisogermacrone 3 with BF3Et2O. When TMS-OTf is employed, 3 undergoes an unusual rearrangement leading to the product 10 with a new bicyclic carbon skeleton. The mechanism of the reaction is discussed.
