Check Digit Verification of cas no

The CAS Registry Mumber 940933-55-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,0,9,3 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 940933-55:
(8*9)+(7*4)+(6*0)+(5*9)+(4*3)+(3*3)+(2*5)+(1*5)=181
181 % 10 = 1
So 940933-55-1 is a valid CAS Registry Number.

Traceless chiral auxiliaries for the allene ether Nazarov cyclization

Banaag, April R.,Tius, Marcus A.

supporting information; experimental part, p. 8133 - 8141 (2009/04/04)

(Chemical Equation Presented) The key stereochemical factors that determine transfer of asymmetry from the chiral auxiliary to the cyclopentenone in the allene ether version of the Nazarov reaction have been elucidated. On the basis of the new insights in
