Check Digit Verification of cas no

The CAS Registry Mumber 677300-31-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,7,3,0 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 677300-31:
(8*6)+(7*7)+(6*7)+(5*3)+(4*0)+(3*0)+(2*3)+(1*1)=161
161 % 10 = 1
So 677300-31-1 is a valid CAS Registry Number.

A very reliable method for determination of absolute configuration of chiral secondary alcohols by 1H NMR spectroscopy

Takeuchi, Yoshio,Fujisawa, Hidehito,Noyori, Ryoji

, p. 4607 - 4610 (2007/10/03)

(Chemical equation presented) Surprisingly stable synperiplanar conformers of CFTA esters have led us to develop a new and very reliable method for assigning absolute configurations of even secondary alcohols having minimal structural differences, such as chiral benzhydrols and α-monodeuterated benzyl alcohols.
