227079-00-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 227079-00-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,7,0,7 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 227079-00:
(8*2)+(7*2)+(6*7)+(5*0)+(4*7)+(3*9)+(2*0)+(1*0)=127
127 % 10 = 7
So 227079-00-7 is a valid CAS Registry Number.

Lipase-mediated kinetic resolution of cis-1,2-indandiol and the Ritter reaction of its mono-acetate

Nakano, Shigeru,Igarashi, Yoshio,Nohira, Hiroyuki

, p. 59 - 62 (2007/10/03)

Lipase-mediated kinetic resolution of cis-1,2-indandiol 5 in the presence of lipase PS was examined. Enantiomerically enriched (1S,2R)-2-acetoxy-1-indanol 6a was obtained when cis-1,2-indandiol 5 was treated with one equivalent of vinyl acetate. Treatment of 5 with two equivalents of vinyl acetate furnished a mixture of (1R,2S)-2-acetoxy-1-indanol 6a and (1R,2S)-1-acetoxy-2-indanol 6b. A route to both enantiomers of 1 was also developed by using the enantiomerically enriched mono-acetate thus obtained.
