22416-98-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 22416-98-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,4,1 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 22416-98:
(7*2)+(6*2)+(5*4)+(4*1)+(3*6)+(2*9)+(1*8)=94
94 % 10 = 4
So 22416-98-4 is a valid CAS Registry Number.

New enantioselective method for hydration of alkenes using cyclodextrins as phase transfer catalyst

Abreu, Artur R.,Costa, Iva,Rosa, Carla,Ferreira, Luísa M.,Louren?o, Ana,Santos, Pedro P.

, p. 11986 - 11990 (2005)

A new enantioselective/inverse phase transfer catalysis (IPTC) reaction for the Markovnikov hydration of double bounds by an oxymercuration-demercuration reaction with cyclodextrins as catalysts was disclosed. Moderate ee (up to 32%) and yields (14-60%) w
