Check Digit Verification of cas no

The CAS Registry Mumber 89827-96-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,8,2 and 7 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 89827-96:
(7*8)+(6*9)+(5*8)+(4*2)+(3*7)+(2*9)+(1*6)=203
203 % 10 = 3
So 89827-96-3 is a valid CAS Registry Number.

A Simple Conversion of 2-Methoxynaphthoguinones to 2,3,4,5-Tetrahydronaphthofuran-4,5-diones. Application to the Synthesis of (+/-)-Trypethelones

Guay, Vincent,Brassard, Paul

, p. 1853 - 1857 (1984)

Structures proposed for trypethelone, O-methyltrypethelone, and O-methyl-8-methoxytrypethelone have been confirmed by synthesis.The required naphthoquinone substrates were prepared regiospecifically in one step by using vinylogous ketene acetals and then converted to the desired products essentially in a novel one-flask procedure.
