Calculate Digit Verification of CAS Registry Number 19598-08:
(7*1)+(6*9)+(5*5)+(4*9)+(3*8)+(2*0)+(1*8)=154
154 % 10 = 4
So 19598-08-4 is a valid CAS Registry Number.

Catalytic cis to trans Conversions; Dihydroxybicycloheptane and 1,2-Dihydroxyindane

Taylor, Jay E.

, p. 1142 - 1144 (1985)

cis-2-exo,3-exo-Dihydroxybicycloheptane (2) was isomerized in aqueous solution by an improved procedure to the corresponding trans-glycol 3 in 71percent yield, using Raney nickel at 80 deg C for 56 hours.Similarly, cis-1,2-dihydroxyindane (5) was isomerized by Raney nickel at 60 deg C in 42 hours giving 31percent trans-1,2-dihydroxyindane (7).
