Check Digit Verification of cas no

The CAS Registry Mumber 75557-01-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,5,5 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 75557-01:
(7*7)+(6*5)+(5*5)+(4*5)+(3*7)+(2*0)+(1*1)=146
146 % 10 = 6
So 75557-01-6 is a valid CAS Registry Number.

Absolute Configuration and Chiroptical Properties of 8-Methyl-1-decalones

Hagishita, Sanji,Kuriyama, Kaoru

, p. 950 - 958 (2007/10/02)

(8S,9R,10S)-(+)- and (8R,9R,10S)-(-)-8-methyl-1-decalones were prepared and their absolute configurations were determined by a kinetic resolution method.The contribution of the methyl substituent was octant consignate but different in magnitude for the axial and equatorial groups, though they were nearly mirror images with respect to the horizontal symmetry plane of the carbonyl group.The trans-decalone (3) was less stable than the cis-isomer (15).This agreed well with the result from conformational analysis.
