Check Digit Verification of cas no

The CAS Registry Mumber 70813-22-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,8,1 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 70813-22:
(7*7)+(6*0)+(5*8)+(4*1)+(3*3)+(2*2)+(1*2)=108
108 % 10 = 8
So 70813-22-8 is a valid CAS Registry Number.

Iron-catalyzed alkenylation of Grignard reagents by enol phosphates

Cahiez, Gerard,Gager, Olivier,Habiak, Vanessa

experimental part, p. 2636 - 2644 (2009/04/07)

Stereoselective preparation of trisubstituted olefins can be easily performed from an Z/E-mixture of enol phosphates by reacting only the E-isomer with a Grignard reagent in the presence of Fe(acac)3. This procedure combines a kinetic differentiation and a stereoselective reaction. The coupling is very chemoselective in the presence of an alkyl chloride, an ester, a ketone or a nitrile.
