Check Digit Verification of cas no

The CAS Registry Mumber 176487-03-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,4,8 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 176487-03:
(8*1)+(7*7)+(6*6)+(5*4)+(4*8)+(3*7)+(2*0)+(1*3)=169
169 % 10 = 9
So 176487-03-9 is a valid CAS Registry Number.

Prompt determination of absolute configuration for epoxy alcohols via exciton chirality protocol

Li, Xiaoyong,Borhan, Babak

supporting information; experimental part, p. 16126 - 16127 (2009/05/09)

A microscale protocol for determination of absolute configurations of 2,3-epoxy alcohols is described. 2,3-Disubstituted (cis and trans), 2,2-disubstituted, 2,2,3-trisubstituted, and 2,3,3-trisubstituted epoxy alcohols rendered prominent ECCD signals upon complexing with a Lewis acidic porphyrin tweezer and consequently provide straightforward assignment of chirality for epoxy alcohols. This method proved to be rapid, simple, sensitive, and reliable for the class of molecules listed above. Copyright
