Check Digit Verification of cas no

The CAS Registry Mumber 612040-87-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,2,0,4 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 612040-87:
(8*6)+(7*1)+(6*2)+(5*0)+(4*4)+(3*0)+(2*8)+(1*7)=106
106 % 10 = 6
So 612040-87-6 is a valid CAS Registry Number.

Conformational effects on lipase-mediated acylations of 2-substituted cyclohexanols

Tanikaga, Rikuhei,Matsumoto, Yoshimasa,Sakaguchi, Maki,Koyama, Yohei,Ono, Kentaro

, p. 6781 - 6783 (2007/10/03)

Lipase-mediated acetylations of trans- and cis-2-substituted cyclohexanols gave the corresponding (1R)-cyclohexyl acetates and (1S)-cyclohexanols in high yields and ee, but c-4-tert-butyl-c-2-ethenyl-r-1-cyclohexanol was unreactive owing to the steric interaction between the axial OH group and the axial H atoms at the 3- and 5-positions. In the cis-isomer the OH group occupies an equatorial position to bind to the lipase, and less bulky axial alkenyl and alkynyl groups might not so much prevent acetylations than an alkyl group.
