Check Digit Verification of cas no

The CAS Registry Mumber 56845-81-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,8,4 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 56845-81:
(7*5)+(6*6)+(5*8)+(4*4)+(3*5)+(2*8)+(1*1)=159
159 % 10 = 9
So 56845-81-9 is a valid CAS Registry Number.

On the C-25 Chirality of 26-Hydroxycholesterol

Byon, Chang-Yon,Gut, Marcel,Toome, Voldemar

, p. 3901 - 3903 (2007/10/02)

The stereospecific synthesis of (25S)-26-hydroxycholesterol with a chiral synthon derived from (S)-(+)-3-hydroxy-2-methylpropanoic acid is described and the Cotton effects of the CD spectra were found not to be a general means for distinguishing epimers of monohydric secondary alcohols or for distinguishing epimers in which the chiral center is in the α position to the primary alcoholic function.
