Check Digit Verification of cas no

The CAS Registry Mumber 881667-67-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,1,6,6 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 881667-67:
(8*8)+(7*8)+(6*1)+(5*6)+(4*6)+(3*7)+(2*6)+(1*7)=220
220 % 10 = 0
So 881667-67-0 is a valid CAS Registry Number.

A hetero-Diels-Alder approach to complex pyrones: An improved synthesis of the spongistatin AB spiroketal

Crimmins, Michael T.,Smith, Aaron C.

, p. 1003 - 1006 (2006)

The conversion of a substituted dioxinone to a pyrone was used in an improved synthesis of the AB spiroketal subunit of the spongistatins. This transformation occurred via a hetero-Diels-Alder reaction of an acyl ketene with butyl vinyl ether. A double diastereoselective Mukaiyama aldol reaction is used to provide the hetero-Diels-Alder precursor.
