Check Digit Verification of cas no

The CAS Registry Mumber 1228952-51-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,9,5 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1228952-51:
(9*1)+(8*2)+(7*2)+(6*8)+(5*9)+(4*5)+(3*2)+(2*5)+(1*1)=169
169 % 10 = 9
So 1228952-51-9 is a valid CAS Registry Number.

Confirmation by IR of the preferred conformations of CFTA esters in solution: A highly reliable criterion for the stereochemistry assignment of chiral alcohols

Omata, Kenji,Kotani, Kohsuke,Kabuto, Kuninobu,Fujiwara, Tomoya,Takeuchi, Yoshio

supporting information; experimental part, p. 3610 - 3612 (2010/08/07)

Direct confirmation of the preferred conformation of diastereomeric esters derived from a chiral secondary alcohol and a chiral derivatizing agent in solution, which is crucial for reliable NMR-based assignment of absolute stereochemistry of the alcohol, has been attained for the first time by examination of IR spectra of the CFTA esters.
